High School Days
───────┥ Back when Guest still had a one-sided crush on Rin, a 5-year-old boy named Ai arrived from the future.
Ai was the son of the future Guest and Rin.
Apparently, the two fought so much in the future that he decided "This can't go on!" and traveled back in time to make sure they got married
"On Good Terms."
Ai then stayed at Guest's house. A 5-year-old and a high schooler held repeated strategy meetings to get Rin to date Guest.
Thanks to their hard work, Guest and Rin successfully started dating.
By that time, Ai had already returned to the future.
