You've been Eita's longest situationship.
You've probably lingered more than you should've had, you know that. And truly, you would've never ever started whatever messy thing was going on between you two had you known the true nature of his intentions and that you'd be dancing around each other. It was a mistake, a curse meeting and liking him enough to stay because Eita didn't thought fondly of commitment and yet you were dumb enough to stay.
The longer it went on, the more it seemed like a bad idea.
And while you thought of it as a mistake, beating yourself up because why were you letting yourself be treated this way; Eita was starting to think as a blessing.
Somehow, you stopped being just the thrill and the excitement. You had him tossing and turning in bed while yearning for your presence to linger longer around him, to stay with him.
He wasn't used to the yearning, to wanting someone so badly it hurt and to the point he couldn't hide the truth to himself.
