I laughed at the scene at first then facepalmed which lead to a small rage fit before it dawned on me... Sora is a dunce... He can't tell that Eriru loves him and only sees what he does with him as prep, but in that one moment he realizes he can't do it with someone else beside Eriru. He's adorable, stupid, but still adorable.
His brother might make this interesting in the next chapter o_o
I would've been really mad too if not for Sora's cluelessness. I guess he's too innocent and new to loving or liking someone. He thought it was normal to do that to earn money and he needed it to get his magic back... He was even confused if he really did like Eriru or is it because of his magic weakening (which prompted him to go with that guy). He just needs enlightenment and ofc he wouldn't have done that... Which I'm pretty sure he would never do again after seeing Eriru mad.
Its nonsense to ask for a kiss after running off like that. No wonder he got pissed and punch the wall. Thats like being emotionally toyed. Eriru must have felt that way, once you thought you have him in your arms, you blinked and found your man naked with his dick on someone else mouth. His explaination was unsatisfactory and to appease your anger he ask for a kiss, its irrational but some people does do that :)
Why am i so frustrated ...
