Eisei, who had been confessed to by his childhood friend and neighbor Tsukio when they were kids, rejected him, and they've been distant ever since.

One night, while he's skipping school after being publicly teased by his ex about being bad at sex, sinking into negative thoughts alone, he reunites with Tsukio in front of his house as he's kissing an older woman.

Under the promise of helping him get back to school, he starts hanging out in Tsukio's room, spending time as if the past confession never happened, and little by little, his wounded heart begins to heal――...

In the midst of that, when he sees a message from an unknown older woman on Tsukio's phone, and despite supposedly liking him, he prioritizes the contact—Eisei tells him that if he doesn't want to be hated, he should teach him techniques since he's bad at sex. His kind attitude suddenly changes, and he's tossed about by Tsukio's teasing yet pleasurable sex――?
