MKON-036 My super serious girlfriend who absolutely wouldn't let me get any suddenly became the prey of a 'www system' group staying at the same inn during our school trip. Usazuki Aika

This girl is my girlfriend, Usazuki Aika. She's an excellent student and the student council president. We've been together for a year now, but she's so serious that she still won't let me do H stuff with her. We made a promise not to do H until we're old enough to take responsibility. But maybe it's fine to wait until we're adults. I want to spend the more important time that can only be experienced now with Aika. One day during our school trip, Aika was taken by strangers who were college students.
