This is actually a 5.5
The story isn't that original, but it isn't bad that you just want to drop the manga. The girl annoys me a bit, she's the usual girl who hates the guy but falls in love afterwards. Same as the guy, he's the usual "I'm cool, I won't like you" guy, but he really loves the girl.
Butttt, this manga is pretty decent for a one shot manga. It can at least have 10 more chapters.
It's kinda sad how this manga has only 1 chapter, the art is really good for a one shot. AHHHH ~
