High School Days
───────┥ Back when Guest still had an unrequited crush on Rin, a 5-year-old boy named Ai arrived from the future.
Ai is the future son of Guest and Rin.
In the future, it seemed the two fought constantly as a married couple. Deciding that "this can't go on!"
To make them marry "on good terms,"
he apparently traveled back in time.
From then on, Ai stayed at Guest's house. A 5-year-old and a high schooler repeatedly held 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.
▶▶ End of Past Arc ＿＿＿＿＿＿＿
After that, the two got married.
And now—.
Guest and Rin have a 5-year-old son, Ai.
The Ai who came from the future back then was the child Guest eventually gave birth to.
Five years have passed, and Ai is now in his final year of kindergarten. Just like back then...
