this is one of my comedian manga so I hope u will have fun
Koizumi Risa, current height 170 cm. Her surname is translated to "small river". A girl taller than most other girls her age. Otani Atsushi, current height 156 cm. His surname is translated to "big valley". A guy way below the average height of a highschool boy.
They're both known all around school as the comedian duo for looking like nothing but funny while standing beside each other. Due to this fact, they've been on one another's bad side ever since they first met.
One day, a new transfer student shows up and he happens to be very tall! Koizumi immediately gets interested in this boy and Otani suddenly proposes a silly idea to Koizumi. The idea is that they are to help each other out to get their respective love interests by all means! Koizumi undoubtedly agrees to this but as in all other shoujo mangas, things never turn out the way people want it to.
