She does like someone besides Yamaguchi, and she tries to meet up with him again, but despite this guy saying he'd come he never actually does, leaving her heartbroken. (Yamaguchi is there with her while she's waiting)
She ends up giving up on him and accepting this isn't going to work out after a long talk with Yamaguchi. Yamaguchi also confesses to her after this. This drama doesn't last very long, only a couple chapters, so rest assured.
