What happens when two childhood friends start to see one another as something more?

My childhood friend Reina, the prettiest girl in school, is about to date the ace of the soccer club...
I've always liked her but was not brave enough to confess.
Is this the end of our friendship? Or the start of a new affinity between us?

Reina and Yō have told one another how they truly feel… but are their bodies a good match for one another?
Worries about physical compatibility have been banished from the minds of these two young lovers… so why not go at it again?
After a full day of doing it, Reina invites Yo to stay the night for round three!
