Nahh. If he were you, would you fall in love with a kid you've treated as a brother? He's pouting his guilt unto him - all familial love. It's understandable since he's still grieving.
I think this is better. We'll see how well written the characters are, especially now that Sejin is still green in the ear. Lot's of shit would flip from our 'moralists' here if he were to see Sejin as a potential partner. They'll brand it as grooming, and I'd have to dislike a lot of bullshits from stupids who keeps scrolling even after reading warnings and just reading with their assholes open.

This comment makes you sound like one of those people that enjoy reading actual grooming yaoi. It's a weird thing to say.
The MC has been an adult this entire manhwa. The fact that the author continues to write them acting like a child is weird and I don't like it... But he's not a child and we've never seen him when he was a child. He's just a very immature and stupid adult.

Nahh, I don't enjoy such shit. In this case, we still have a lot to see here. The characters are well written so far. The bottom is still grieving and projecting his familial love to the top. The top, on the other hand, is still in middle school and still discovering himself. Hence, I said that this set up is better then them jumping on the gun of falling in love. We'll see them realizing more of themselves, especially the top.
Regarding 'moralists', there are a lot of readers who disagree with relationships that started when one of the pair is still young (even if they're one step away from being 19) as they think it's disgusting despite threading and reading how the story unraveled. They voice dossapointments to the author and brand it as grooming the moment they mixed flesh.

He is not in middle school. He's 20, a legal adult, at the start of the series.
If he was in middle school this would be super grooming. The fact that you think he's in middle school and are still reading this shows your gooning to grooming because you think grooming is hot.
I completely disagree with you though. Showing either character as a child meeting the other character as an adult immediately makes it a grooming porn. What I mean by that is grooming is the fetish that is being catered to, even if you don't see the grooming directly... The whole point of showing the child and the adult is to appeal to people who have a grooming fetish.
And that's a problem. It shouldn't be allowed, it shouldn't be accepted, and good people wouldn't make excuses for it.
There's always some degenerate gooner who claims because they don't see every little piece of grooming that it didn't happen but that's not how grooming works and that's not how manhwa works... Especially when so often the main character is the adult. When you're viewing the story through their point of view why would they show you the things they've done wrong.
However, logic dictates there's no way a child would willingly sleep with an adult without grooming happening.

The fuck? Did you shove you hand in your ass while reading my replies?
He found the top when he was 17 and sees his dead sister in him. He is pouring familial love unto him. HE IS PROJECTING HIS GRIEF. He doesn't see him as a potential partner at the moment as he is still grieving. Furthermore, the top may be in his legal age but he's green in the ear in the concept of love and commitment. If seen in the standing of understanding a person, he could be put in a position where he's still confusing his feeling for his benefactor. THEREFORE, we still have a lot to unravel in their story - a lot to see. The characters are well written so far and this set up is flowing well. DON'T WHINE FOR THEM TO JUMP THE GUN AND FUCK JUST BECAUSE THEY'RE IN THEIR LEGAL AGE, fucker.
The point of that grooming as I've said (let me repeat it for you, stupid shit), is from the perspective of 'moralists' readers who brand benefactors as groomers. They perceive or tag stories like these as grooming without understanding the story. Take a look at Amber Alert and Tree Without Roots. That's the point, but you suddenly flipped and blurted your shit.
Tell me, what were you disagreeing with me when we were pointing the same thing? You twisted my words and then tagged me an one who enjoys grooming when I clearly reflected there the words 'OTHERS'. I also highlighted CHARACTER DEVELOPMENT. I even put '' for the word MORALIST, yet you walked in with that tag plastered in your forehead. Go read again my words. Take a picture of your undergrad degree, master's degree, or even your PhD degree to make sure no "stupid" word was attached before your name.
Hes still going on with that sister memory thing with the kid? I thought by now hes given up that and got feelings for the kid.
