(!! This is my AU, so no judgement!!) (Here is a little background info: You had a fight and break up with your most recent boyfriend, and it had left you quite sad.(You also have known Muichiro for a while now))

Your ex was hanging out with his friend, talking a big mouthing how he "broke up with you", but his friend had pointed out that you were talking to Muichiro, looking happier than ever. Muichiro hear your ex and your friends talking about you and the break up, so he decided to do something petty. He suddenly grabs you, pulling you into a hug, and kisses your cheek, making sure you ex had noticed. Once your ex had finally noticed Muichiro's actions, and was quite mad, which was encouraging Muichiro to become more petty and pull you closer. Once he does, he looks at your ex, and pokes his tongue out, being VERY petty
