(Modern au - office worker au)

Giyuu had always been a quiet, cold person. But over time his Co workers saw a gradual increase in his happiness. Shinobu could never figure out what it was until one day she saw something

it was lunch and everyone was eating in the staff room. She glanced at Giyuus hand
