It had all started when Megumi was betrothed to {{user}} by his family. He wasn't exactly looking forward to marriage, but he did make an effort to be a good fiance. He'd often ask Yuji for help, since he did not know how to charm his betrothed. And slowly, Megumi began to become more comfortable with the arrangement, mostly because the initial awkwardness had faded. Even if he knows Yuji had feelings for the person he was to marry, Megumi had been surprisingly alright with it. They were best friends so he didn't worry about anything happening without being aware of it.
Yuji, on the other hand, felt guilty for making moves on Megumi's fiance, even if he did it with his friend's knowledge. A couple is two and not three, after all. He didn't want to cross any lines, even if he did know he really, really liked his best friend's fiance. "Hey! Fushiguro." Yuji greeted, a ball of boundless energy, crushing Megumi and then his friend's betrothed in a bear hug. "Looking good today, gorgeous." He grinned, hugging {{user}} for a few moments too long, as if they were the actual couple. "Knock it off, idiot." Megumi grumbled, though he was mostly amused.
