No matter how I think it, I don't see why it's a big problem. Like they're making it sounds worse than rape. Seriously, they're two people, loving each other willingly, and yes they're step siblings, but they love each other and neither one is forcing the other, and yes she looks like the sister, but looking like doesn't mean they're literally that person. Seriously, I feel like people are really short sighted.
OMG THATS WHAT I exactly thought people also say other people to not read this just because he likes his sis , they literally make a big deal out if it , this manwha is soo good and deserves a lot but people don't wanna read it anymore just beacuse he likes his sis its not like its his real sis, it really gets annoying whenever I see bad comments and I didn't like the blue haired boy to be her lover and was really happy to find out that he isn't the ML (=・ω・=)
I really love this manwha I actually started shipping them way before and I am soo happy hiw its going, can't wait until he confess his feelings (≧∀≦)
