7 Days

I suggest the following training regime:
50 Push-Ups!
50 Sit-Ups!
50 Squats!
And then a brisk 5 KM Run!

Why the half Saitama? Simple, she may like his hair.

Numbers in the title? Hand†˜s Rule (obviously invented by me) states this needs to be a series...

Well, it was obvious from the start where this would end up, and only more so once her boyfriend turned out to be blatantly using the money she made from this for his own stuff, essentially just pimping her out to get money for himself. The cheating was just a bonus after that, even if it did help her finally truly realize how bad he was. Good job, Otaku-kun, excuses aside, you know she already can't live without the care and pleasure you showed her.

Only took him 7 days to make her fall in love with his dick. Too bad it's gonna take more than 7 days for her to fall in love with him. She a hoe.

Her boyfriend though, wow. He's all like, "Sure, I'll let you have her for the week, so fuck her, and be sure to send pix and payment."
And she goes along with it willingly, too. I wonder if he has a cuckold fetish or just doesn't give enough of a damn about her (Like he's cheating or something)...Or maybe he just wants the money.
Turns out to be a mix of him cheating and thus not caring about her that much, and also for the money.
Well, our guy certainly made the most of the arrangement, and as a result she now knows how physically compatible they are, and by that ending...Well, there really isn't any reason for her to turn him down. And hey, she does give him a chance, asking him to get buff and to make her fall in love with him. I'm sure he can do it, definitely.

This needs a short sequel lol.

Next time she sees him he’ll be built like he was drawn by Hirune-Sensei.

Let's get this straight:
Yuuya was basically pimping his girlfriend Minagawa out to another guy,
and cheating on her besides (probably while she was busy with Otaku).
Can you say: "Douchebag of the Year"?

To make things even worse, Yuuya probably kept all the money (70,000
yen) for himself, and he even had the gall to ask Minagawa to send him
fap fuel (pics of her fucking another guy).  Super-Douchebag of the Year.

It seems that Minagawa and Yuuya seriously underestimated both the earnestness and the "mojo" of 'Otaku-kun'. Even before the story was over, Minagawa had been conquered by Otaku-kun's superior sex skills (compared to that of Yuuya-kun). Of course, she won't easily reveal how she's become putty in Otaku's hands ... it's sort of a Tsundere thing. Although by the end, it's a foregone conclusion. Nonetheless, to maintain the illusion of control, she calls on Otaku-kun to "buff up". Be Careful, Minagawa-chan; the end-result might hit you like "You Wa Shock"! As for Otaku-kun, Do Your Best ... You Lucky Bastard (GRR)!

"APPROVED!" ðŸ‘

"get as buff as your dick" seems like a fair deal for a vanilla sequel!

Needs sequel where MC becomes rip makes the girl unable to deny her feelings over him!

Warning, this chapter contains off the chart levels of tsundere cuteness.
Her body knew she lost before she did ❤

I feel like the mangaka just wanted to put Maki from Love Live into a commercial work so they did.
