Title sounds wrong, probably machine translated.
I'm guessing that the girl (delinquent in the title) was pushed by her wimpy boyfriend to sell her body so he could roll on gacha games, botha re young and stupid and she was just a little more mature than him, but blinded by love she did it anyway.
She got lucky and her first client treated her well, so she didn't had to search for multiple old salary men.
She was seeing her love crack because a random guy was treating her better as a partner, I'm guessing that redhead got tired of her body or had a bigger experience for his looks, or different boundaries, or simply a kid personality so he didn't know how to treasure her or thought of her love and loyalty and pussy as obvious things.
Then she visited him one day and discovered he was cheating and understood she wasn't anything but a cash cow to him.
Seems like he understood she was the right girl later, possibly tanned girl thought of him as a fuckboy and didn't stick around, he tried to talk with her but it was too late, or he used the worst words.
So he is the one that got cucked by selling the girl that loved him for gacha.

So what's the salaryman's story? It looks like he has a family? Did his wife cheat on him?

@squall23
Yes, his wife was cheating on him with many men, even his own daughter ok with him divorcing while the wife wanted more money making the father moment with his daughter awkward.

You know? I'm still salty about the other work of his due to chapter 3.

This dude shouldve just made this and not that damn 3rd chapter that fucked up everything from that last story. Nobody gonna forget about that shit till he either makes it right or retcons it. And even then that may not be enough.

you know what frustrating? It's already the finished story, with pretty much normal people in it.
Yes, NTR, but here it's completly undestandable. Yeah, this dude saw it's coming, with how he treated his gf.
So her falling for the guy, who was kind to her, was good in her eyes was good. And she didn't fall right of the bat.
Even the ending is set in stone: salaryman divorsed his cheating wife and merry gyaru, who is pregnant.
But nope, auther thought that it's not right, so he retconned few moments and now this is somewhat a sex-gang, in 2 and 3 chapters... stupid.
So for me, only this exists, others are just different story with look-alike characters.
