A/N I will be completely honest here and admit that this glorious idea never crossed my mind until you suggested it, thank you!
Meet the Future Sister-In-Law - Toukomaru version
“I thought I’d never see you again.” Komaru practically wheezed as she broke her run by hugging her brother as tightly as she could.
Makoto returned the embrace with just as much affection if not more, his hands patted her gently as he chuckled freely. “Well I can’t say the same.”
Komaru pulled back, shocked at his choice of words. “How cruel! You mean to say that you didn’t miss me at all?”
“No, that’s not it, Komaru. I never said that.” He shook his head and smiled reassuringly. “I just meant that I was sure that we’d meet again.”
“Geez, always the optimistic one.” She found herself returning the smile just as easily. “It’s good to know that part of you hasn’t changed one bit.”
“Well it’s my only redeeming point you know.” He joked with tears in his eyes as he looked at her with sibling pride.
“Yeah, I know.” She sniffled as she wiped a few tears that had already flown.
It was a long road just to get to this moment. This moment where these siblings were finally reunited. It was a painful journey for each of them and it was riddled with despair all throughout but they never gave up. They didn’t lose sight of hope and so they persevered. Until finally, they were reunited at last. Not everyone had survived but they were grateful that at least both of them were safe. Here, holding each other, this much they were more than grateful for.
“Ugh! Okay, we get it. You two missed each other!” Touko unceremoniously interrupted their moment with an annoyed groan. “You already hugged on it, isn’t that enough drama? Don’t you think that this is dragging for too long? We have a schedule to run by you know.”
“Touko!” Komaru jumped back from the hug just so she could properly glare at Touko who seemed unaffected by it. “Give us a break, will ya?”
“It’s good to see you again too, Touko.” Makoto chuckled and greeted his friend goodnaturedly. He would have hugged her too but she declined so he just offered his smile instead. “Thanks for taking care of Komaru.”
Touko appreciated the gesture although she hardly showed it. Her words lacked their usual bite though so maybe that was as good as it’ll get. “Yeah you should be. She didn’t exactly make it easy for me.” She scoffed.
“Hey! That was uncalled for!” Komaru objected.
“I call it as I see it.” Touko stated as a matter-of-fact.
“Meanie!” Komaru stuck out her tongue at her to which Touko merely frowned at her childish antics.
Makoto on the other hand, watched fondly if not slightly amused by their display. “Well aren’t you two cute together.”
And just like that, the banter was broken.
“C-Cute?!” Touko stammered right before her whole body became stiff and unresponsive.
“Aaand she’s frozen…” Komaru sighed. They still needed to work on Touko’s tolerance for compliments.
“Ahaha, my bad. I forgot that she does that.” Makoto sheepishly apologized. “So I’m guessing that Touko will be joining us?”
And all of a sudden, the lighthearted atmosphere was replaced with a growing tension as it was Komaru’s turn to freeze, her nerves shot.
“Actually, there’s a reason why Touko’s dropping in on our reunion…” She started hesitantly and then backed out at the last second. “You tell him, Touko.”
That was apparently enough to bring her back to her senses.
“M-Me?” Touko looked back at her indignantly. “Oh, h-hold it right there. No way! We already talked about this and you agreed that you’d tell him.”
“Only because I lost a bet!” Komaru pointed out in the hopes that she could get away with it.
“That you still agreed upon!” Touko hustled. She crossed her arms and tilted her chin upwards as she urged her on. “Come on, Komaru. Grow a pair already and fess up.”
“Not really my kind of idiom considering I’m a girl.” Komaru grumbled in defeat. She knew that it was useless to start this fight anyways. “Maybe we should have stuck with the whole secrecy plan.”
“You’re the one who was all "if we’re going to do this then we’re going to do this properly, starting with a no secrets policy” so take responsibility!“ Touko ordered her.
"And you should know by now that I hardly put any thought into my words. It was a spur of the moment thing!” Komaru argued, her cheeks were dusted pink. “Also, now? Really? Can’t I have a few minutes to prepare myself? I don’t think I have the guts to tell him right now.”
“Hm? Tell me what, Komaru?” Makoto innocently asked.
“Hey! Big bro!” Komaru all but jumped when he joined in the conversation. As soothing as his smile was, it wasn’t enough to calm her nerves. Oh, god so was she doing this? Apparently so. “Well! You see…” She fumbled as she tried to put together the words. “Uh…” She already knew what to say but had trouble actually getting them out of her mouth. “Touko and I…” The words seemed to be stuck in her throat as she coughed in an attempt to get rid of the itch there.
“Oh, for crying out loud! Just spit it out already.” Touko raised her hand in exasperation and gave Komaru one last literal push.
“Arekindasortadating.” Komaru spewed hastily and all at once. She had to pry her eyes open since she winced right after. But she knew that now that it was out, all that was left was the verdict and so she anxiously stared at her brother for any reaction.
“Oh…” He merely said and fell quiet for a while. Until he smiled again. “And?”
“And… that’s it.” She replied, not quite sure what else he wanted her to say. That reaction kind of fell flat compared to her expectations. “Wait, did you hear what I just said or do you need me to do a repeat or?”
“I heard you the first time.” He laughed for a bit and then settled for a lopsided smile as he confessed, “I know.”
“You…” She stared at him incredulously. “You already know?”
“Well you two weren’t exactly subtle about it.” He explained with a cheeky grin.
Komaru could practically feel her blush of embarrassment. “What gave us away?” She squeaked.
“The flirting and that one phone call.” He easily explained.
“See! I told you to check if you actually ended the call!” Touko chided her.
“Hey! It was just one time!” Komaru pointed out.
“Clearly one time too many.” Touko retorted.
“I said I was sorry!” Komaru deflated.
Before the two could continue their argument, Makoto thought it was best for him to intervene with a round of applause. “Congrats on your relationship.” He then placed his hand over his sister’s shoulder and said, “Don’t cause too much trouble for Touko, okay Komaru?”
“Isn’t this supposed to be the part where you’re the overprotective brother and you threaten my girlfriend instead?” She raised an eyebrow, confused.
“Normally but it just so happens that your girlfriend is much more reliable than you.” He playfully ruffled her hair.
“Ack! Betrayed by my own blood!” She dramatically fell on her knees as if struck by a blow.
“Hmph, you must be so heartbroken over the fact that as strong as your brocon game is, his siscon isn’t so much.” Touko slyly teased her.
“Not again with the brocon. Touko, we’ve been over this. You’re never letting this go, are you?” Komaru sighed in defeat.
“It’s alright, Komaru. I’m sure Touko would be more than willing to comfort you.” Makoto smirked at both of them.
“S-Shut up!” They both shot back at him accompanied with blushes and deathglares to which he merely laughed them off.
Teasing aside, it looks like the introduction as girlfriends was well received. They were only visiting though so maybe next time, they’d be introducing themselves differently then.
