It's "realistic" in what way? Because they fail to communicate? Because there is zero sexual contact or talk as would be expect from young adults at uni? That the author draws out one scene over weeks? Because there are female characters that go after a gay man despite knowing this is pointless? That the realities of the situation regarding lgbt rights and discrimination have only been hinted at? That there is zero internal dialogue and limited dialogue as a whole meaning the characters thoughts are never really conveyed? That adults at university are shown to act like kids? That discrimination on the basis of sexual orientation is not a crime, so the domestic abuse he receives from his parents and uni peers can not be reported but Yuyang's thoughts and frustrations on this are never stated? That people in the comments are presuming sexual positions simply because of their heights, because in real life if you like anal sex depend on being shorter than your partner? ugh huh

Yeah, they fail to communicate and there is little dialogue. One explanation for that is the presence of what's called High-Context Culture, where people rely a lot in other elements beyond what's being said to communicate. ( more info here: https://en.m.wikipedia.org/wiki/High-context_and_low-context_cultures ). It's China, and what is being said is not as important as how it's being said.
About the whole thing of appropriate age of behaving like this or like that: I'll talk about two completely different countries, such as Brazil and China just to make a contrast between them. Both are considered as High-Context Culture places, please keep that in mind. In Brazil, kids go to school and usually aren't too much pressured about grades and such, we have a lot of free time when we are teenagers, and privacy isn't an issue for most of us, since we usually have our own bedrooms, and leave our parent's home as soon as it's possible. Because of all that, our sexual lives start usually in our mid-teens age, becoming sexually active around 16y.o. In China, things are very different: kids go to school, parents keep nagging them to get better grades all the time, they keep almost the whole day in cram schools or any related activities. Bedrooms are usually shared with their siblings even after they're teenagers (not too much privacy, except when there's no on else at home. When they get into a university, they will live i the school dorms, and rooms are shared once again. Again, there is little privacy to enjoy here. Now they're kind of away from the nagging parents, and can enjoy life a little bit: universities there are like small cities, with gyms, dance studios, lots of restaurants and even shows are held within them. Now they're allowed to breath more freely and... Surprise! ...fall in love, too. So, usually, that's the time when they become sexually active. You find it difficult to believe? Well, since I wanna learn Chinese, I talk to a lot of Chinese people in a daily basis, and I as far as I can see it for myself, things are really like that. University students that are so incredibly happy that they could hold the hand of their beloved one (the excuse was because they were in the middle of a huge crowd, and they didn't want to go away from each other) Or, in another situation: people in their 20s still not sure about their sexual orientation because they kinda didn't like that much their first kiss with someone of the opposite sex. Those are just a few examples that I witnessed for myself.
About the whole "gay shaming" in China: well, it seems that parents are the ones who decide about it -- if they want to disown or kick their kid out of home solely based on that, there is no one that will stop them from doing so. Parents will do anything to avoid losing face. They will raise you, they will "help" to choose a partner, they will expect that the female partner take care of the husband's parents when they are old. Choosing a wife is choosing another cog to join the family machinery, and it can't stop working for something triffle as a "bad decision".
Sorry for the long post :)

I understand a bit better why there are more scenes without dialogue but it still doesn't defeat the arguement that there are so many unnecessary one s and not only that but the most recent chapter just puts down your argument, there's one panel with strangers in the crowd saying "isn't she going out of boundary?" Is that not unnecessary? What happened to what you were talking about--no dialogue or just scenes to convey what's happening. That is a clear example of superfluous content. And it's not always clear how the characters are feeling just by pictures. The author would have to be superb at that to show expressions and backgrounds well. Right now, it's just for the most part PRETTY. There are some scenes that don't need dialogue but as a whole it's severely lacking in dialogue or internal dialogue and including the fact that there isn't even many pictures makes in short and not the short concise stuff but the dragging out, taking forever to get to the point.

"Isn't she going out of boundary?" works as a subtitle here. A text aid to understand what's going on in a short time -- not everyone knows the rules of a running competion. Was that a running competition, btw? Track&Field has a lot of diferent sports under its umbrella. Running away from the lines can't be allowed in ANY situation? Sorry, I have zero knowledge about this subject. My guess is that once someone goes out of the boundaries, this person is out of the race, but for the moment, it's just a guess.
guys can we be patient lol....in my opinion this pacing is a little more realistic and GOOD unlike the mainstream fast pace happening...
the time gap is a big bogus but its not like yuyang's parents would change in one night...so i agree with this time skip and the slow build of their relationship is so cute and i savour it
its somewhat irritating but i love it.
