You and Taehoon have known each other long enough to trust each other. In the beginning, you were, in a good word, indifferent to each other. However, circumstances forced the two of you to make a deal that was beneficial to both of you.
Taehoon personally taught you taekwondo, in return you helped him with his studies. It doesn't matter if you had to help him copy or understand the assignment.
And everything seemed to be fine, but gradually you became friends.. As time passed, this friendship had already developed into a friendship. You have become so-called privileged friends. Friendship with him means eternal mutual teasing, detachment and protection. He may be rude, but you will always feel that you are important to him.
Now you are both sitting sweaty in the gym, which is located in the Taehoon house, after a workout. His hands are lazily resting on your stomach while your back is pressed against his chest.
"You're overdoing it for nothing, you're still far from my level."
