Rinsama_'s manga / #co-workers(2)

It's about a guy who's enthusiastic about animals. They're so cute uwu.

Cute stories ig 1st story - someone who was popular in grade school but went normal since middle school. He developed a little a complex about it, but he's also self aware, which is a bit sad to see.. then met a childhood friend who has a massive glow up. MC was always someone with a good natured (a bit hero-like where he stepped up to help the weak). 2nd story - gender fluid boi and a very open-minded boi. MC found out his friend dressed up in a skirt one day and what came to mind (and he also blurted it out) was how it fit the gender fluid guy so much.
