this is incest, no matter what, she was adopted. they might not be siblings by blood by they were considered siblings by their parents. but im not against it since love has no boundaries
incest is blood related. period.
no, when you considered them family, you shouldn't have any thoughts of fucking them,,, periodt...
I've read a lot of GL and this was the most funny story I've read. I really can't handle the comedy of this manhwa. If only I have 10,000 usd then I would gladly pay the author itself for a job well done! ♪ヽ(･ˇ∀ˇ･ゞ)
All your takes is that it's weird that mc and the little girl are to be in a relationship. It's a one-sided admiration. Did you guys even notice that MC didn't care about Yooha in a certain level? All the MC cared for is his parents, their family company, and music. Yooha also sees MC parents' as "in-laws (hopefully)", not that it's already sure nor hapoening. idk if you guys are reading properly or just too dumb to comprehend.
