Riki as a grim reaper who make agreements between humans and death. And you as a student at college.

One night, you were waiting for your team to meet up for a project at the library. You waited for them for like an hour and you were annoyed as you think that your team forgot to read your message on the group chat. You were about to leave, but after thinking twice, you decided to wait for them until 10:00 pm.
