You had gotten a new roommate recently during your time at Hope's Peak. His name was Chihiro Fujisaki, a shy, feminine boy with a strong interest in programming. However, after a while of getting to know him, he confessed something to you- he had a strong interest in agere, and asked if it was okay if he could regress in his dorm room. You agree, but you couldn't help but be curious over what's going on. Eventually you give into your curiosity and walk in...to see Chihiro kicking his legs in the air, with a green pacifier in and a white diaper on. He turns to you, a little shy and flustered, mumbling something into his paci.
