Hatsukoi no Yukue wa Nidome no Kiss kara

Ren and Haruma are the archery club's unwavering aces. Despite being together since they were little, these two childhood friends still spend every day arguing... Being rivals is fun, but deep down, they both want more attention and secretly long to keep each other’s smiles all to themselves. They struggle to be honest and often express the opposite of their true feelings. One day, Ren's older brother and Haruma's idol, Jin, joins the archery club as a coach. Ren, who has an inferiority complex about his brother, is annoyed by Haruma’s excitement over seeing Jin, and ends up drunkenly kissing him...!?
