1st Story (Bachi Bachi):
The two ukes, who are third years, both fall in love with the same kouhai, who is a first year.
The long-haired uke looks soft and a little girly. The short-haired uke is buff and hairy, he looks a little older than both the seme and the other uke. The seme is smaller and thinner than both ukes. This is a threesome.
5th Story (Hatagaya Lullaby):
An older writer and a goth-looking singer live in the same apartment. The goth fell in love with the writer due to a book he wrote that really resonated with him.
Older uke, younger seme.
Note: I didn't bother reading the other stories because I didn't like them. Particularly, I didn't like who was seme and who was uke.
