For your headcanon request: The first time Komahina left the WOH alone for a date night, Komaeda was worried that the kids would be alright and was texting them to check in every so often. Hajime, in comparison, seemed pretty calm. But deep down every time the kids texted back something like "Jeez, Dad, we're fine! Chill!" He would let out a little sigh of relief, too, because darn it he's the SHSL Dad of course he wants to know for sure that his kids are fine.
I love this one bless
