Review of Sing "Yesterday" for Me

Okay, I guess I know what the author tried to transmit with this story; love is confusing and all that stuff. However, I think that the very ending of the last episode screwed it up. [SPOILERS AHEAD] I don't know what people see in Haru. Don't you think she is a bit of a stalker? After being rejected by Rikuo several times, she keeps going after him, waiting for him at his work and house. In the last chapter, I kind of understand why Shinako and Rikuo split up at the end; they are confused and trying to understand what love is. But then, Rikuo goes afterHaru (who APPARENTLY seemed to finally give up on Rikuo) and all of a sudden he says he loves her. Honestly, I don't understand.
