What Should I Do After Reincarnating as the Bottom in a Korean Webtoon?

After working late-night part-time jobs, Liu Junxing drops dead from exhaustion. He wakes up to discover that he's become the protagonist, who shares his name, in a Korean webtoon his neighbor's little sister lent him.

In the comic, the protagonist has a tragic background. His father owes two hundred million and ran off, leaving him to cover his seriously ill grandmother's medical bills. Meanwhile, he'll meet the chaebol seme while working at a coffee shop, the delinquent seme at his convenience-store job, and the broad-shouldered neighbor seme, who's a gang boss.

Most importantly, they all have their eyes on his ass!!!

Liu Junxing, who'd been working two part-time jobs and was about to buy a home before coming here, finds half a length of rope in his shabby rental and thinks: I guess there's no absolute need to stay alive...

Snap.

The rope breaks.

Liu Junxing searches the entire room and discovers he doesn't even have enough money to buy a rope...

The miser Liu goes berserk. Did his deadbeat dad borrow all that money to play the stock market on Japan's nuclear wastewater!? Who would lend two hundred million to someone whose table legs are all chipped!? Was it ghost money!? And are there no straight men in this world!?

[Bonus Scene]

Liu Junxing gets up early one morning and opens the door, only to find seme three blocking the entrance, his brow furrowed so tightly it could crush a mosquito.

"Liu Junxing, you'd better think this through," the gang boss says menacingly, holding the door open with one hand.

Liu Junxing pinches his palm, looking small, pitiful, and helpless. "I'm sorry, but my place is tiny. I really don't have room for a double-door fridge."

The butt-protection campaign of a pitiful little pure-love-loving miser. The endgame seme is undecided, but the story ends 1v1.

This isn't aimed at any particular Korean webtoon. I'm a sucker for this stuff and I love reading it. [P.S. There are actually lots of pure-love stories.]
