#07 Unforgettable sweet sound of the fart

"Romance" …comes suddenly and leaves swiftly just like Onara(fart)…
Onara Makoto & Onara Tsubasa have been friends since they were children.
Onara Tsubasa likes Onara Makoto, but Onara Makoto thought of him as just a childfood friend who has been around always.
However, one day Onara Kaori appeared, and that changed the situation.
Will their relationship progress more than "childhood friends"?
