Lol typical women mindset only acts when someone else tries to steal the guy she likes. All her planning went down the drain, she could have fixed their relationship ages ago when she became just like him. They even live near the same area lol, since this isn't a harem manga she's probably gonna lose the heroine battle and be broken or with little chance accept it and be friends with Shuuji and the girl which is what i hope.... or fuk it just put a d on both of em.
