Monsta X: when you hug them and say "I'm so thankful to be with you"
Shownu: is taken aback when you hug him at all, since he really wasn’t it expecting it. He’ll squeeze you tightly and smile to himself, asking you if everything is alright. When you respond and tell him that you’re thankful for him, he’ll burst into a grin and pull you into an even tighter hug. He’s not the best with being vocal about his emotions, but he won’t let go of you and shows you how much that meant to him.
Wonho: he’s in such a hazy and pleasant state, that he won’t be able to respond for a couple minutes. He’d just hold you and let you shower him with affection, but he really can’t tell what it’s all for. He’ll pull back slightly and smile at you, in awe of how easily you take his breath away. “I’m more lucky and thankful to have you, love…I can’t imagine what I’d be like if I haven’t met you. Promise me, we’ll stay together forever, yeah?”
Minhyuk: he’s gonna pick you up and spin you around until you’re both a dizzy and giggling mess on the couch. While never letting his eyes off yours, he’ll take your hands in his and search your face for something, as if he’s wondering if you’re being genuine and not just saying this out of nowhere. Will surprise you by suddenly pressing his lips against yours, and sighing when finally pulling away. “I love you. More than anything. I’m so blessed to have someone like you.”
Kihyun: like Hyunwoo, he’d be confused at your sudden burst of affection, and pull away to ask if you’ve gotten yourself in trouble or ate his favorite snacks. He’ll laugh when you tell him off and that you were just trying to be romantic, and he’ll apologize in embarrassment while holding you tight. “I know, I’d be thankful to have me too. But I guess since I can’t clone myself, I’m glad it’s you who I get to share myself with.’
Hyungwon: will wrap his tall limbs around yours without really needing a reason to, and doesn’t question why you’re suddenly being so cute. He’ll chuckle and rest his head on top of yours, rocking you both back and forth until you hit him with those words…and man he feels like he’s gonna burst in tears. Tries really hard not to fanboy in front of you bc his stomach is full of butterflies and he can do nothing besides kiss you and returning the affection.
Jooheon: squeals of joy when you wrap your arms around his waist and bury your face in his shirt. Is gonna squeal even more when you tell him that you’re thankful for him, since he’s always felt like you were a miracle when you walked into his life so he should be the one thanking you. Cups your face in his hands before squishing them and kissing your lips, telling you that you never fail to make him happy and thankful.
I.M: turns really serious all of the sudden, I think this would hit him pretty hard unlike some of the rest. He’ll hug you back and not pull away, but he’d still think about if he’s done something to make you act like this. Goes into a full speech about how you’ve changed his life, and that he’s always thinking of ways to be a better boyfriend, since he feels like he doesn’t deserve you. Good luck trying to not cry tbh.
