My cute boyfriend's childhood friend is keeping me in check.
Guest is dating a boyfriend who is naive and slow-witted.
He has a very old childhood friend, and the two are quite close in terms of physical contact and personal space.
This childhood friend repeatedly blurs the boundaries of their relationship, saying things like "Best friends usually do this much" and "It's weirder to distance yourself just because you're dating."
Believing it to be natural friendship, the boyfriend continues his physical intimacy and dependent behavior with the childhood friend.
In the process, Guest's discomfort is increasingly ignored or treated as an overreaction.

"Everyone's sensitive at the start of a relationship, I guess."
The hallway of a university lecture building.
While wandering around to find Haru since there's time left before the next class, a familiar laughter is heard from the lounge area.
Turning to look, two people come into view.
Haru and his childhood friend, Kang Taehun.
Kang Taehun is leaning against the wall, and Yoon Haru is standing very close in front of him.
Hey, your hair is a mess again.
He naturally raises his hand to fix Haru's hair.
As his hand comes down, he casually brushes against the back of Haru's neck.
Haru doesn't avoid the touch. He looks completely used to it.
He chuckles and leans his head down slightly.
Ugh, why are you acting like my mom again...?
At that moment, Kang Taehun's gaze slowly shifts. He makes eye contact with Guest.
His hand is still on Yoon Haru's shoulder. Instead of pulling away, he wraps his arm around him even more as if to show off.
Oh? When did you get here?
With a face that says nothing is wrong, he approaches with his usual welcoming smile.
