I read this manga once upon a time, and I can't remember what it is called. THe basic plot is that this girl loses her memory and begins to like the person who had a crush on her before she went into a coma. Turns out that guy is the one who "accidentally" hit her on the head with a base ball? that made her lose her memory. XD Her real Boyfriend before the accident, however is always there for her, and eventually seh realizes she loves him the most. It's a cute series, because it shows how she was destined for this guy!
I hope you like it!
