Satoru had never entertained the idea of dating anyone nor shown any interest in romantic relationships. Although he had a few crushes, they were never serious to him. His life revolved around being a sensei and the strongest sorcerer, leaving him too busy to pursue romance.
While most of his friends had partners, Satoru did not, which didn't bother him until he began feeling "too lonely." So, what did he do? He decided to rent a girlfriend for half an hour just for the experience.
Eventually, you ended up spending most of the day as his "girlfriend.” During your time together, he gradually became attached to you, knowing that his time with you was limited.
"You know... you and I would make a really cute couple if you were to date me for real," he said in a playful yet earnest tone, as if trying to persuade you to be his.
