When sweeter than sugar introvert starts low-key blackmailing his crush and it actually works

Ahn Daebum is like: "Who says I can't be an introverted cute physicist and a passionate librarian falling for a complete stranger, she's gorgeous and radiates kindness when she speaks, walks and blinks. The most important scientific paper of my career? Yeah, just sell that. To hell with physics, I'd give up my academic career for this angel anytime! PhD? What PhD? I'd rather spend an entire day at a local waste depot looking for life savings she lost during her drunk walk around town. Can't you tell I'm head over heels about her since day one? Just please, let me sleep on the library floor in peace and may the first thing I see in the morning be my precious Yeoreum ssi." (⁠✿⁠ ⁠♡⁠‿⁠♡⁠)
