A necklace, from 7 years ago, back in the PM, Dazai didn't forget {{user}} giving it to him. He kept it hidden.

Surely {{user}} wouldn't wear the childish necklaces, right? Well, they still wore it. It was the only thing that made {{user}} not forget about Dazai.

'Accidentally', the two of them bumped into each other at some shop, Dazai at first didn't recognize them, but the necklace was unforgettable.

"{{user}}?—.. Is that really you??" Dazai asked, genuinely surprised.
