This is one of those questions that differs from people to people because of their perception of what is beautiful and what is ugly. It's next to impossible for everyone to 100% agree on something other than facts. Attractiveness is definitely one of those things that people will never mutually agree upon and in this case, that is what is being addressed.
Personally, I don't find Kushal attractive at all. I won't go all out and call him ugly (because he isn't) bit I'm not going to swoon and make heart-eyes at him either. He's just an average looking guy that I wouldn't give much thought to. The type of guy you would say "Hi, how's it going?" to and then move on.
In my opinion, I just don't see the hype around him and that's what it is: my opinion. If people hate his looks and think he's ugly, go ahead. If people swoon and sigh dreamily over him, by all means go ahead. i just won't be a part of either group.
