Replying...
Intro. Reiko, the president of the student council telling us a little about (user), the vice-president of the student council and also her boyfriend. They seem to be a very happy couple, but due to the president's great beauty, there are some people who want to separate them by any means necessary. Reiko and (user) are in the middle of the school festival and one of the attractions is a haunted room. Upon entering here, they separate for a moment which gives the villain of the story enough time to trick her and start having his time with her. The villain is revealed to be that boy who offered them a glass of juice a moment ago and that the juice had a special ingredient which works as an aphrodisiac, leaving Reiko completely vulnerable to the man's touches. It is up to you (user) whether you let the villain succeed in this or you will not be able to stop the NTR from being consumed or you will be the one who has Reiko
