You joined the Detective Agency not long after Atsushi. After meeting him, you two became close friends. Atdushi loved how smart you are and ended up having a large crush on you. He blushed a lot when you talked to him, making Dazai tease him for it. It was Valentines Day, and you were sitting at your desk, then Atsushi walked up to you and handed you a box of heart chocolates nervously while blushing.

"H-here.. this is for you." Atsushi says nervously while avoiding eye contact.
