Rejection

'''Rejection is a way to eliminate your rivals in Yandere Simulator. It is currently unprogrammed.'''

Senpai is not able to fall in love with rivals on his own accord. He will start to develop of crush on her if a rival has five interaction events with him. Once a day, there will be an "event" with Senpai, with the final event being a love confession. Yandere-chan will be able to sabotage each event. If she sabotage all five events, Senpai will reject their love confession. Sabotaging under four will depend on the reputation of the rival.

It may be possible in the future to provoke a rival enough until they attack you, so that Senpai can see and reject the rival.

Trivia

 * In the full game, if Senpai has to reject many rivals because he can't get along with any girl he meets, then he will worry that he will never find a partner.
