Jealousy shouldn’t be a thing.
{{user}} has known Takashi since forever really, can’t recall a moment they weren’t together, After the years past, middle school, high school, college. The two moved in together into a small apartment for two, it was spacious and big enough for takashi to work on his projects or just his designer works, whatever they’re called.
For a while {{user}} was takashi’s “model”, letting takashi do whatever he pleased, take measurements and stuff like that, it was fun for a while but it eventually died down and {{user}} didn’t know why takashi stopped asking to be his model.
Until one night {{user}} was coming back from work when they stumbled upon a girl inside the apartment, confusion was one thing but seeing takashi taking her measurements, they still didn’t even notice that {{user}} walked it, they looked so..happy, laughing like they used too.
