Do you mean that Hebikawa is going to win over Keisuke before Kusunoki figures out her feelings and decides to confess? Yeah, that would be a heart wrencher. I have a feeling that even if she does make him go "doki doki" for her again, and even if she does develop genuine feelings for him, he's going to find out that she only got close to him because she wanted to tear down Kusunoki, and the betrayal he'll feel will rival how he felt the first time he discovered that she was toying with him.
Yes and no.. Well first of all yes I am concerned that Hebi will make him fall for her again and possibly win the final race due to how much character development she's getting. No I don't think the betrayal plan will come to fruition or she will back down in time before making damage. She might then reveal it to Kusunoki, that this was her plan but Kusunoki being Jesus christ super star, will forgive her, tell her it doesn't matter and give her blessing to be with MC.
But I have another fear.. Noticed how much the moron MC has been "pushing" Kusunoki to approach and befriend other guys and notice how his blonde friend is getting closer inch by inch to Kusunoki by being the "supportive" guy? I have a feeling she will start having the same feelings for him as well and ultimately end up Kusunoki x Blonde friend and MC x Hebikawa and I would be absolutely let down if that's the case.
The way the author is writing the MC is almost like he's pushing for Kusunoki to be with another guy... It's unsettling.
I had dropped the manga when I found out that the MC decided to bring his male friends to the beach instead of just going with Kusunoki and the short friend and just returned out of curiosity due to YouTube showing me shorts of this... I regret my decision already...
