MC helps a down-and-out grandpa mainly to get into the good graces of a female celebrity and to accomplish mission objectives. From the way these events are written, MC does not initially feel any obligation to help. The System just hastily assigns him missions whenever MC meets someone unfortunate.

So it's not apparent to readers that MC does anything from the goodness of his own heart, which is problematic.

Compare that to "I Really Am A Superstar", where the MC Zhang Ye at least has his own sense of righteousness (whether it's misguided or not) and is capable of making his own decisions about who to help with his powers.

Although the MC Shen Huan eventually isn't stingy about his help and does a lot for the grandpa, it's mainly due to continued incentives from the System. MC starts jokingly referring to himself as an emperor (internalizing) and keeps it that way. Which is no longer funny and shows that he's quite a pretentious p*ick.

This behavior shows up in a few odd ways.

MC believes in his own pseudo-image of an aloof genius (he initially created that image way because he didn't want to be pestered too much by being famous). He doesn't easily accept requests even from his allies/friends, just to preserve that s*upid image (after his talents were already exposed).

By c214, he even states that "if someone doesn't brings you benefits, there's no point to maintaining a relationship over time. EVEN IF THOSE PEOPLE ARE YOUR PARENTS", which is pretty f*cked up especially considering the Confucian values of Chinese culture. Maybe the author was being an utter dumbass in wording, but that's literally how he wrote it.

For a transmigrator from Earth, you'd expect that the MC Shen Huan at the very least pretends to hold on to some previous cultural values and not be so immediately accepting of polygamy. This is a pretty common format in most modern-day, non-apocalyptic transmigration novels.

It's even stated that polygamy isn't common in the new world.

MC was just a normal 30-yr old office worker that transmigrated. He wasn't a cold-blooded killer. Wasn't an ex-soldier. Wasn't a cunning businessman. Wasn't a poor struggling civilian. None of the usual novel tropes. Just regular Joe.

And yet, the MC just agrees with the situation and immediately sets his mind on collecting potential wives since it's legal....

Author even mentions some of his potential parent-in-laws are monogamous due to love for each other! Which just highlights even more that the MC is a hypocritical p*ick. Ugh.

In other novels when an MC gets transmigrated to a world with s*aves, at least they usually make some effort to NOT participate in s*avery. Here we have the total opposite.

he beat the crap out of some random thugs, inflicting maximum pain on them, while saving a random girl. No, he didn't need to go that far. No, he didn't feel the slightest twinge of guilt or rejection to causing pain. Unsurprisingly, that wouldn't be the last time. While the system tries to fix his unambitious ways, it rewards his behaviors.

I recognize that he acts caring with friends and family, but the narrator points out every so often that he only gives them opportunities because they can make the most out of the opportunities. If they couldn't, he wouldn't help them. Aside from the people he regards as future wives, everything is strictly done based on how it makes him look or whether or not he can complete a system mission, and even with the future wives, well, he wants them to be his wives in the future because they're beautiful and talented/rich, so I don't think that counts! I wish he could help a friend without having to remind the readers that he's only doing so because he expects to get something out of it later!

he joins a NBA team and flies off to America for 100+ chapters, almost completely ignoring the main storyline. In and of itself that's fine, but the blow-by-blow of the basketball games coupled with using real celebrities was both redundant (because most of the games weren't that interesting) and disconcerting (because Americans don't speak like that, and those don't celebrities don't act like that, at least not quite that publicly).

In the last few chapters the author has started moving away from basketball alone, but we haven't reached the finals yet after 100+ chapters of basketball starting from just the playoffs...

MC is going to have a shitload of wives

he has a childhood friend, a fellow musical colleague (whom I don't recall ever stating she liked him but the story says so), a fellow actress (maybe?), and a couple girls from school. That's about all I can remember

as of now he hasn’t done anything with any of the girls but there are like 3 that are obviously going to marry when he gets older (he’s only in highschool)

every time he makes a large sum of money the system gives him a mission to donate it to “build his character” and because the future superstar shouldn’t be worried about a small amount of money now. He has to donate to get the rewards such as songs and movies or else people will find out he’s a hack if he suddenly stops producing work.
