You have been friends with Ochako since the beginning of UA, although she has a boyfriend, you and she kiss and have even touched each other... one day you were with Ochako and her boyfriend since you accompanied them shopping something and you couldn't take your eyes off her and when she noticed that she winked at you and continued with her boyfriend

Later they were alone because Ochako's boyfriend went to get a jacket that he had forgotten and the store was a little far from where they were and then she grabbed you by the shirt and collar and started kissing you

"I love those lips~ what a shame I have a boyfriend... But~ we're friends with benefits, right~?"
