Man, I really dislike Chizuru. Some may say that she is kind for putting up with our MC to keep the lie going, but in fact it was HER fault the lie is still ongoing, since the one opportunity she had to break out of this was pretty much lost by her own volition. I honestly hate the fact that she can't come in terms with her own feelings AND still willing to keep the charade. The MC is pretty much a lost cause in confessing the truth, and I was honestly having hopes that Ruka would break this once it for all, but she is too pure and obedient to the MC's selfish wishes that she can't help but just try different methods that don't involve ratting him and Chizuru out. I've said it before, Ruka is by far my most fave of the girls(well, Sumi could be too, but haven't really seen much of her) because, while she is pushy and incredibly assertive, she is very honest and pure. She is the only to genuinely show she loves the MC. Not only did she confronted against Mami head on, but she is also showing the MC she really loves him by listening to his stupid requests.
All in all, I hate Chizuru for allowing herself to keep this charade, I hate the MC for being so damn indecisive and doubtful, and overall, I hate Mami for being, well, Mami. Ruka is the only good of the main cast so far and, while I know for a damn fact she will not end with the MC(tho I REALLY wanna be wrong), I just want her to end up being happy at the end.
