Wild to Strawberry
|
A boy who is enamoured by his classmate, confesses his feelings/asks his school mate to date him, and to his surprise, the school mate agrees. In fact, the latter (aka the seme) ends up taking the relationship more seriously than the uke.
However, since Wild is a one shot, the feelings are rushed. You can call Seven Days an improved version of Wild.
