the kiss literally lasted one panel, he FORGOT, he DONT CARE anymore bc it was CALCULATED and it had REASON. He is moving onto his next plans without a second thought about it. It wasn't to push romance onto the series and she's the only one who, rightfully, blushed bc she's a teenager and some dude kissed her. Tbf she sucks ass, I don't like her and I hope she's not end game.
ppl always bitching about romance in these types of series when "romance" is literally always at most half a chapter long or less. God forbid a character has depth and relationships. Most of these relationships aren't even explored until the end of the series and it's just a hint that MC will live a regular happy ending at THE END.
