Oof I really hope this doesn't end in a "Well clearly you were just in denial about liking men your whole life lol" that's a pretty degrading way to go no matter which side of that you are on.
I do wonder how long it will be til they actually address that they mutually have feelings for each other. I mean it's become incredibly apparent in this college arc that they feel the same way about each other but, it feels like they are dragging it out when it comes to a confirmation between the two that it is the case.
Honestly this would be such a terrifying situation to find yourself in. Half the world is gone and no one cares. In fact you are the only one who even seems to remember that the missing half even existed. All the people you knew and loved are now acting completely different. I'd be scared shitless personally.
What a nice little 4koma. It even managed to have a character arc that would've taken some other stories about 4+ chapters. Very noice. Also owo what are gonna do on the bed sempai?
This reminds me of that episode in Gokaiger where one of the main bads Insarn falls in love with the red ranger from Carranger only yurified. I look forward to more of this series.
