OHSHC Fanfic - It's Fine That I'm Not Me (HikaruxOC)

"Kaoru Hitachiin, I would like you to be my tutor."

When Seiran Hirai approached Kaoru and asked for him to be his tutor, Hikaru never planned on going in his brother's place. Still, doing so wouldn't hurt, so Hikaru went along with it.

But things didn't turn out how he thought it would.

Everyday after school, Hikaru would have to go to the homeschooled child's mansion and tutor a boy who has already mastered every subject there is! So why does he even need a tutor when Seiran should be tutoring Hikaru?

Reasons, perhaps, that will not be mentioned.

But that didn't matter to Hikaru. In the end, he decided to continue watching over Seiran without understanding why.

Maybe it's because he's starting to develop feelings for him...
