It was a manhwa where they are trapped in a mall, I supposed, or a building. The other character has a crush on MC and he devised a plan to confess on a sort of building. I remember at the end that the building breaking down was supposed to be sort of a harmless joke but it was a real danger.
Is it this one?

There's this guy who is like very aromantic and or asexual but is a BL artist. He wants to draw poses and I think hires a guy to do the poses for him. But amidst that situation, the guy who poses for him falls in love with him I think. The BL artist guy wears glasses.
Haven't read it in a while but it sounds a little like Oh! My Assistant.
