The ML says to the MC that if after a couple months of their engagement/marriage, and he doesnt want to do it anymore, he could back out if he wanted to. Not only that, it is also explained that because of his (ML's) status, a lot of people constantly used his name to create fake scandals, making his private life seem messier than it actually is in the media. When they have their engagement, ML completely cuts off clean any possible messy misunderstandings and is very considerate of how his actions might impact MC

When ML confessed, he wanted to wait before he got his answer from MC... because he didnt want MC to regret it as he was still in his youth.

Just because I like you, I am willing to be obedient.

But you can't rely on the fact that I like you and let people bully me. This would ruin my liking for you...

He would not be petty and weak because of a crush.

ML confessed to the MC around chapter 30th after their first kiss during a photoshoot

Not really enjoying the way the ML assumes he has the right to order everything about the MC's life because he is the older one and the MC is still in high school (but 18). While it's obvious it comes from sincere care for his well-being, he's a spouse (with no parental experience), not a parent, and the MC is 18. Yet the MC is expected to be obedient, if the ML tells him to do something and the MC uncomfortably says it's not necessary, the ML still insists that he do it. Sure, it's not anything bad - going to the hospital when he has a cold, overseeing his homework, accompanying him to school - but he ignores the MC's rejection of these things rather than respecting his qualms or discussing it with him and getting his agreement. Sure, he SAYS things like he'll grant his request, or that it's OK to tell him if he's angry or upset, but he doesn't follow through when it's small daily things that he's decided is best for him. I prefer much more equal relationships.

I also just don't enjoy the way "obedient" spouses (wives) are so popular in Chinese stories, and how it's always especially appealing and virtuous for the shou to be the obedient one because they see the shou as the wife in the relationship. And I suppose in this instance it's respect for elders, too... in Chinese culture, the technical "generation" one belongs to seems to matter even more than actual age, and I suspect one of the reasons the MC is so obedient from the start - and virtuous for being obedient - is that the ML is the same "generation" as the MC's parents and aunt, even if he's not old enough to be his father (normally).

I'm not really vibing with the MC's love when it's mixed with a fear of getting scolded.

I assume that some of these aspects will improve, but it's clear there's a fundamental type of pairing going on here that isn't really my thing. I do like the doting older partner x younger partner dynamic a lot of the time (e.g. Love You 59 Seconds or Your Distance... wait, why can I only remember the names of the uptight uni professor x student ones!), but this is doesn't have quite enough to enjoy for me.

Finally, I'm not actually finding the characters or the plot very interesting. There's really not very much going on apart from homework...

Edit: I was NOT disturbed by the age gap itself, just didn't enjoy in how they chose to portray it in this instance. I also think it's a pity they translated Uncle to English. It has different connotations for an English speaker, but for a Chinese person it's similar to calling a boyfriend Ge, Oppa, -Nii as a sign of respect and closeness but isn't in*estuous. Unfortunately, it does feel a bit uncomfortable to hear the MC call his husband "Uncle" for my native English-speaking self. Not a deal breaker, just a pity.

i also didn't understand why is it usefull to marry for the ml
