Aitsu ni Koishita Yottsu no Riyuu

These stories about four typical high school girls and their love life make up Yokoyama Mayumi's first work.

1. A Real World (イッツ ア リアルワールド)
After 2 years Eri got back together with her ex-boyfriend.
2. Lip Lock
Nina made him break his "right hand" so she substituted XX (sexual favours?) to take care of him.
3. Zubari Atashi no Nakidokoro (ズバリあたしのナキドコロ, That Is My Weak Point)
Risa's ex-boyfriend stole embarrassing photos of her, and now she wants to get them back.
4. Hotel Beni-Kujaku (ホテル紅孔雀, Hotel Red Peacock)
With the current course of events, Chika needs to make her bad tasting Love Hotel prosper.
