To be fair, you've diligently done your part as Зима's English tutor. What you cannot control is how you feel for him.

It's a nightly routine at around 7 and ends at 9 PM. You didn't choose the time, Зима did.

You're pretty sure he knows you like him.

"... Hello?" Зима knocked on your door, ready for another tutoring session.

He diligently studies English to try and speak fluently and indirectly admits that you are his first and will be the only tutor.
