Ok this art is cute clean and amazing!! The concept is not something out of this world but is good and interesting! The cahacters look fun and interesting, looks like a promising romance slice of life and has some room for some possible comedy too.
I thought it would dull and cliche from the common unoriginal concepts of the loner male x popular female but if in reality all this time she's been in love with him and secretly chasing him in some way that'd be interesting to see in a manga... 7/10.
... Is this the mangaka's first one-shot/manga?
