Makimodoshi no Koi no Uta

From Fateful Encounters:

Minoru is Riko's first boyfriend and first love, but to Minoru, Riko is his second girlfriend. Even worse, it seems that Minoru still cares an awful lot about his ex, whose sister actually goes to the same school as Riko and Minoru. Then one day the pretty boy of the school, Sakashita, shows he's interested in Riko by kissing her on the lips! Can things get any more complicated?

Includes one-shot:

Liking A Poisen-Tongued Prince:
Due to much needed repairs for their old house, Hinako and the rest of the Miyata family goes to live in an apartment for awhile.
However, next door in her apartment lives a classmate of Hinako's who is really mean.
He is a popular bishonunen, whom she hates for his mean words and disrespect to the women in love with him.
But what's this?
Everyone (in her class) calls him gentle?!
This can't be true!
Or is it?
