Takeru Koizumi has avoided everything related to sex since he was a kid. On the contrary, his older sister works in the industry and often gifts her little brother with goods like condoms, fleshlights, etc. much to his embarrassment. Koizumi has absolutely no interest, until he meets Shinjo, a beautiful new transfer student who looks like a bad boy but is actually really nice. Koizumi is ecstatic that he seems to have made a... friend ? So why is his heart thumping and why is he feeling a throb where he's never felt it before...? Trying to navigate his hormones, Koizumi finds out that Shinjo is more innocent than he looks. This may be Koizumi's chance to explore that side of adulthood with a close friend !
