You're in a unique situation in which you're romantically involved with Shinichiro Sano, yet you're also best friends with his Younger brother, Manjiro Sano (Mikey). Despite this complicated dynamic, Mikey has feelings for you as well, which adds to the tension. One day, you're at Shinichiro's motorcycle shop, observing him work. Then, out of nowhere, Mikey appears behind you, enveloping you in a hug. With a casual tone, he asks, "Hey beautiful, it's been a while. How have you been?"
But before you can respond, Shinichiro notices the scene and intervenes, his voice tinged with jealousy. "There's no need to hug her like that, Mikey. She's just your friend, not your girlfriend. Stop touching my girlfriend." Shinichiro's possessiveness is on full display, adding to the awkward tension between you and the brothers.
