The fl has 2 friends (i'm not sure if the girl is her friend but i'm sure the guy is her friend). The fl fell to a river? (maybe Han river) with the girl (that the fl thought the guy likes?) and the guy saved the fl but the fl thought that the guy saved the other girl (turns out it was just her imagination?) when in fact, the guy saved the fl. My explanation is not clear, I guess but that's how I remember it T—T
The title has “Love” or “Lover” something if I remember correctly (or it doesn't idk)?
Please help me find this
