I actually really like this story, cheating and all. It really sucks for Natsuro, but this story isn't really about him. He's the collateral damage showing the cost of wavering and not being honest with yourself and others in a relationship. Importantly, Hiro and Kazu both realized their mistake, and ended their other relationships. Thankfully it's just fiction, and there's a spinoff for Natsuro! (though that poor guy still has to deal with some drama in his own story lol)
