Although I hate cheaters, the uke is the one who is least to blame since the other two are fools for playing along.
1.He was the only one who knew what he wanted and was willing to do anything to get it. He told the sis from the first moment that he liked her brother, so she knowing everything forced the relationship because of her ego of wanting the uke to like her.
2. The mc is shit for having hidden from her that his partner was cheating on him with him. He is also stupid for staying with the uke despite everything.
3. In conclusion, the worst character is the sis, for being cuck and homophobic.
