I'm sure he has admirers here and there. I think the novel might have mentioned it here and there.
I remember that in chapter 102, during the class competition, the sing-off that Hajin was a part of was supposed to be about 1 chapter long. When he sang, he pretty much rizzed the audience while Rachel's misunderstandings deepened in regards to the false rumors about Hajin's unrequited feelings towards her due to the lyrics.
If you want, there is a male cover of Hajin's chosen song on YouTube. It's What If by Tae Yeon (cover by Roel)

Smh, I can't find the novel anywhere unless I want to log into a freaking website, I don't want to log in just to read a few chapters, pissing me the fuck off bruh, I really wanted to read that part but not so much that I want to give my gmail to another website yet again, wish someone could just sent me the exact text written in the novel here just to satisfy my curiosity

I found a link to the Korean raws of the novel. If you have Google Chrome, you can use its translator feature to mtl the novel.
The last panel, Hajin looked so hot lol, how is he not considered as attractive by their standard, he has great taste in clothes/fashion, has a mysterious vibe in the eyes of most, he's like the top student when it comes to studying, how is he not more popular than most combined, excluding the main leads, like Hajin should have a lot of secret admirers, I think he's shorter than the guys( unless my mind is fucking with me) but he's a short king, a hot lone wolf type of "bad boy" ykwim???
