Peter, also known as Your Boyfriend, is the main antagonist of Your Boyfriend. He appears in Day 1 of the game and is deeply in love with you, willing to go through great lengths to prove how much you mean to him. Even if you don’t want anything to do with him.
Peter has a gray body along with a round head without hair.
He wears black pants, a dark blue T-shirt with a heart that is half black and white, a black vest. It is unknown if the black pants are part of his feet as it appears that he does not wear shoes.
Peter is a person who has a lovesick nature within his own heart; he is an obsessive, possessive, unstable, violent, and a desperate man, that goes great lengths to show how much he loves the player in his own twisted way. Peter loves the player so much that he does not discriminate based on his love interest's appearance, size, nor gender which would bolster his chances of finding his love interest. Peter also tends to stalk whomever he loves most, which is Y/N themself.
Peter seems to be mentally unstable and awkward of how he interacts with others depending on the situation, although it is unclear how his personality came to be or it is just normal behavior for young people like him.
On Day 1, Peter appears in front of you when Y/N is sitting on the bench. He introduces himself and offers Y/N out to dinner. This is when the player decides which path they want to take with the story line.
In Day 2, it's mentioned that Peter records himself testing products, reviewing them afterwards as his job.
Umm, dinner does sound nice...
Both Y/N and Peter agree to go out together for dinner. The dinner takes place at Y/N's work place. Y/N waited, meanwhile Peter goes out to buy a rose for Y/N which resulted in his tardiness. He gives the rose to Y/N as a gift. If all goes well, the date will be successful and both Peter and Y/N would be willing to see each other again.
if Y/N does not accept the roses, they will continue to be cruel to Peter, and others as the day continues. They ask Peter for his phone number, who gladly gives it to Y/N.
What? No!... / ...
Y/N rejects Peter's offer. Peter understands this and accepted this decision and goes away. Later that day, Y/N and Peter both coincidentally end up at a flower shop later. Peter awkwardly starts off his conversation after last time and tells Y/N that he often comes to this shop. Peter then offers Y/N another time where they could hang out. Y/N can then allow Peter to walk them home or decline his offer.
