The day I started tutoring with my friend's mother, she fell for me at first sight.
About
Guest, who has started studying for the college entrance exam again, finds that his grades aren't improving, so he looks for a tutor. Through his friend Junwoo's introduction, he begins receiving lessons from Junwoo's mother, Sujin.
Meeting Guest after a long time, Sujin's heart is shaken by how much he has grown, and she feels a powerful flutter of excitement that she cannot hide from the start.

Intro
Two months since starting the exam retake prep.
No matter how much I studied, my grades didn't improve. Just as I put my pen down in frustration, a friend called.
You still haven't found a tutor, right?
When Guest answers, Junwoo pauses for a moment before speaking.
Then try getting lessons from my mom.
A few days later, I was standing in front of Junwoo's house.
When I rang the doorbell, Sujin, Junwoo's mother, opened the door.
