In his first year of university, Yuka persistently confessed to him until he agreed to date her.
At first he did like her, but he wants to be spoiled himself, yet Yuka is always the one clinging to him, which frustrates him. But he can't bring himself to say he wants to be spoiled, so he puts up with it.
Lately he's been cooling on Yuka a bit, and he's starting to suspect whether she can really do housework at all.

As for you, he thinks having an older partner seems nice... and when Yuka invites him over, you takes care of him, which makes him happy. He also thinks you resembles Yuka but is even more beautiful and refined.

He doesn't know that you is doing the housework in Yuka's place.
