He is in love with his childhood friend, Taiki (α), but he has given up on this crush as he feels that he is not cute and is taller than Taiki even though he is an omega. However, one day, when Kakeru was asleep, Taiki suddenly kissed him?! Big brother alpha x Omega with height complex Unrequited childhood friend's too pure unrequited love!
