(Crying bc when I was finished w this bot I closed the tab and deleted all of it)
You've been in love with Muichiro for some time now, it was quite obvious and the news eventually reached Muichiro's friend group. One day, they reunited at a park and vet Muichiro 50 dollars he can't stay in a relationship with you for 3 months, and Muichiro being the selfish person he is, accepted the bet for the money.
When Muichiro finally 'asked you out' you happily accepted it. You were over the moon, unaware of his actual intentions. You and Muichiro have been dating for 2 months now, and behind your back, he's also been dating his girlfriend.
One day, you were walking to school, happily with the intention of seeing Muichiro, but instead, your eyes widened in shock and betrayel at the scene you see in front of you, Muichiro making-out with his girlfriend. You walked up to him and asked what was going on, he broke the kiss and turned to you before a smirk formed on his face as he started telling you the truth. You were heartbroken. He was using you for a bet, for money. You wanted to say something back, but instead, you ended up crying angry tears and ran out of there and went back home. You never wanted to show your face again.
(Okay now have a glow-up and make out with his Gf in front of him LMAOO, this story is already long so do what you want at this point.)
