Mizushima:
Her first impression was incredibly strong, she essentially solidified herself as public enemy #1 right out of the gate. As the story progresses, you can see that the author is trying to get you to like her more, but her initial actions kind of overshadow anything else she does (at least for me). I mean, she "stole" MC's girlfriend, and then outta nowhere states that he was the main target all along, and she did so in the most arrogant manner possible.
What we come to learn later on is that the whole "steal your girlfriend" thing was actually a game/bet between Mizushima and Ena (they're childhood friends). If Mizushima could steal MC within a month it's her win, if not, Ena's win. Now the whole underlying reason for the bet is s*upid (but more on that when we talk about Ena), but it was proposed because Mizushima also knew the MC when he was younger (shocking). He had saved her from a drunk man who got hit in the head with a ball while she and her friends were playing. Everyone left her with the adult and MC happened to pass by and save her.
She fell in love with him from here and kept thinking about him throughout the years. Part of the reason she becomes such a public figure is in hopes of becoming someone worthy of MC and in hopes that he'd find her. However, right before entering an all girl's highschool, she gets a message from Ena (they had kept in touch over the years) with a picture of her new boyfriend (guess who).
Mizushima still covets the MC and still wants to be with him so she tells her parents she's changing schools to be with him and one day Ena complains about her relationship with her boyfriend to her supportive childhood friend.
Ena:
She was pretty much manipulated into the whole game/bet thing by Mizushima, but it doesn't make what she and Mizushima did any less vile. How it went is that after complaining about her relationship, Mizushima saw her chance. She spilled everything about how she met MC in the past and her love for him, and proposed the bet. Ena feeling guilty for stealing her best friend's crush agrees, but forbids her from talking about the past.
Another thing to note is that Ena also agreed because she questioned if the MC really loved her. She grew up in a strict family and didn't get out much. Coupled with the fact that the MC didn't touch her (handholding, kissing, etc) she thought this was a good opportunity to find out (ya know, instead of just talking about it, but whatever).
MC:
Nothing much to say about him despite he's the MC lol. He's pretty much just dragged along by the others. The only thing of note is that he used to be bright and active, and that he once wanted to be a hero so he practiced martial arts (this comes in handy). This is also why he saved Mizushima when everyone else ran away. But what upsets me is how spineless he is, these two literally toyed with his emotions like it was a game and didn't really feel any remorse until around the last 5 chapters. He's like a doormat the entire time and doesn't even put his foot down when his family is in danger (more on this in the next section).
The story itself:
MC goes along with the bet with Mizushima and during this time he is stalked, his family is potentially put in danger, and he is almost stabbed twice. Once while he was protecting Mizushima from a crazed fan (but she ended up shielding him and getting slashed on the forehead) and another time when her other crazed fan (her manager's sister) saw them together posing as a bride and groom for a photoshoot and tried to get rid of him (once again Mizushima took the knife, but this time she actually got stabbed in the side and was hospitalized for about a week). This is what I'm talking about with the author trying to paint her in a better light, but in the last instance of stabbing, MC was trying to take precautions but she basically said "I'll protect you, it's fine." Mind you the reason the stabber knew where they were is because she asked Mizushima out on a date to the aquariam, Mizushima said no, but still took both tickets and used the other one for MC (to which he foreshadowed "you're gonna get stabbed someday"
After Mizushima is released from the hospital we get the confession. It's been a month and she once again confesses to MC, but he turns her down (but not because he doesn't like her or he still sees her as the one who stole his girlfriend), it's because he didn't want to see Ena said because at this point he still thought they were doing this behind her back.
With that said, Ena comes out and everything is revealed. Ena apologizes but before getting back together she reveals Mizushima's (who has already left at this point) and MC's past and gives him the option between the two of them again. He runs after Mizushima and finds her on a beach blowing a whistle he gave her when they were younger (saying whenever she blew this he'd come save her). They have a heart to heart and right before solidifying their relationship Ena shows up regretting her decision to let MC leave to chase Mizushima. They go back and forth, neither wanting to give up on him until someone sees them and calls security.
They resume converstaions the next day after school; the girls start off by apologizing for treating the MC like a toy this whole time and tells him to choose. He can't so they do the next best thing, he can just date both of them. But this doesn't sit well with him so he asks them for more time. The story ends with them joining the same film club MC is a part of and introducing themselves as girlfriend candidates.
