Synopsis: 4p, anyone also can top/bottom (seke). There are romance. Whenever the characters get together, their role (top/bottom) can change. All 4 of them have no morals. Also, please don't look for 3 views in a NP novel... A silly plotless novel about daily life, the sexy time will start depending on the situation.
