I'm sorry but the idea that it's wrong to reject someone because you're not attracted to them is (common, but) ridiculous. OF COURSE you'd reject someone you're not attracted to! Of course looks aren't everything, but it's often the start. Its also normal to find someone attractive because of their personality, and then they just look attractive to you because its THEM, but you need to KNOW THEM for this to be the case! Not to mention how unbelievably DEVASTATING it is to find out that your partner doesnt find you attractive, even if they love you. He asked out a guy that didnt even know him, you can't be shocked that you're rejected! And it turns out he was right to do so, considering he ended up having a shit personality, huh.
It's not shallow, it's marketing babe!
Of course you will not date with someone you're not attacked to! but then don't say that you will fall in love with that person in any context because that's not true. You are just not being honest with others and yourself. Just say that you weren't in the same page in that moment (being not attacked physically even though it is superficial, it is still a reason). The rest, It's just being hypocrite (from my point of view of course). I don't know why you took it personally when it's just an opinion. No need to be passive-agressive BABE ;)
Relax, your mental health will thank you for it :)
Tbh i wasnt really meaning to come off as passive aggressive, if i did sorry about that. this is honestly just how I write. I wouldn't exactly say that I take this personally, i have never experienced anything even a little similar to this. It's more just that, like i mentioned before, it's a common sentiment that i see, its more of a pet peeve then anything.
I'm not really sure where the "will fall in love with that person in any context" thing came from though. If its a reference to the Manhwa I haven't finished it yet. In a reply I mentioned that I dont really speak for whether the characters are shallow or not, if thats what you're talking about, because like i said, im not sure.

Sorry but I didn't like how the uke rejected the seme just because of his looks when he was just a kid.. Like it was quite cruel... and then years later the seme is hot... so now yes, I can fall in love with you! So the story is just superficial and frivolous.. and then, both saying that it didn't matter when and how, they would have fallen in love with eachother.. LIARS Σ(  ̄□ ̄||).
In conclusion, the rest of the story was fine! I liked it in general terms but the hypocrisy is just there..
