he's selling his services
i say whatever, it's consensual, and waayyyyyyy better than the rape him and he falls in love with you scenario that most yaois got going on
also it's kinda realistic, especially for peeps around that age with a poor background, and gotta provide for their young ones/siblings and it's hard getting a job to get involved in the sex industry. ain't no shame in that, imo, he's just doing what he gotta do to provide for himself and his brother. same as if he got a job as a customer service rep, a bank teller, or a receptionist, it's all the services industry, one in the same.
i say bring ya self some money, and in the process, ya might get a honey!

When he tian is beating on mo all the time. Like i know, i get it, it’s for humor or whatever, but that ain’t funny anymore and it’s not cute. I get so happy during those moments that they have of just adorableness but when he hits him (and this applies to the other couple too) it iust erases everything....or like it just...changes everything. Like at first when they weren’t close it was easier to look past it, but now that they’re developing such a heavily romantic relationship, i can’t look past it as easily.

i kept reading after the 1st ch cause i thought this will get better, but ch after ch i just see a man getting bullied by a rich spoilt kid who thinks he can have everything....and i'll be damned if i stick around for another chapter

I feel you man. I don't even know what the mangaka is going for here because one second it's rape ad the next panel he/she draws a cute shibi panel with the rapist in a car whistling as if he is the most innocent character ever. Does the mangaka want us to like his non-existent cute side? or is the mangaka going for the rapist foul vibe?
for me I've promised myself to stick arounf only until chapter 10 and if this unbalanced "violent bratty rich rapist/ overpowered submissive weak uke" thing continues for 2 more chapters then I'm out

I think it's just a very dark manhua, not meant to be cute.

The Nessie, the UFO beam and, the aliens being the UMAs, which disected his privates. This is all symbolic and foreshadowing. The UFO beam stands for the extremely bright lights at an infirmary/hospital, or the beam lights doctors use to check you up. The UMA is the school infirmary nurse, and the dissection is the doctor raping him. The Nessie that he was talking about while getting raped is the doctor's (as vulgar as it sounds) penis. He did have a 6th sense, although it translated to others as though he was insane. That's why when his friend realizes just what exactly he's been talking about, he says "I've seen a UMA once in my life."

Also I think this may have not been riku's first time getting raped because his friend says the first time Riku saw a UMA was in second grade. His friend also says whether it's a tendency of his or luck, makes him an easy target (you wouldn't make conclusions like that unless it's happened before). Also Riku seemed to zone out quite quickly as though it was a coping mechanism. Riku also said "why? Why me...?" This sounds like a response to something that has happened more than just once. So I think Riku was raped for twice.
i have a feeling the ex-girlfriend is only his ex because she found out he's gay, and he only dated her before he found out he's gay or out of pity or something
well i mean she did say "was i a hindrance" and so i have a feeling this means she knows something (▰˘◡˘▰)
