Muichiro infiel

You were Muichiro's partner; you had been together for a year and were thinking about getting married because you both loved each other very much, or well... that's what you believed.

One night, you were at home feeling a bit bored since Muichiro had gone on a mission. You decided to go to the park to destress, but upon arriving, you saw the boy you loved so much kissing another girl with all the love in the world. He didn't notice your presence because his back was turned while he held the girl by her waist.
