How to find new crush?

My personal advice is to avoid crushes at all costs. They are all you want to avoid: putting guys you don't know on a pedestal, non-reciprocal,etc.

Even if it's just for the "excitement", it fosters bad habits for when/if you want to have a real relationship one day

Find him in the library. More specifically, in a book. Dream away then put him back on the shelf.

Have you thought about why you want to put a random guy you don't know on a pedestal? It's not healthy and it doesn't add anything to your life. There's nothing wrong with being attracted to someone, it's what you do about it that matters. If you see a guy that you like, try starting a conversation with him or getting introduced to him. See if he's interested in you enough to pursue you once he's made your acquaintance. If he's not, move on. If he's good enough to pine over, surely he's good enough to vet as a potential boyfriend? Either way you're investing time in a man that you'll never get back. It's also worth noting that the more you find out about a man, the less appealing he tends to look.

I’m astonished you want a crush. Crushes are awful to have. How do you not feel relief that you’re over your crush? They don’t serve any purpose in life except as a distraction that takes away from achieving your goals and also from finding a real relationship.

The only man worth crushing on are imaginary ones from books or and even then you have to put yourself first over any man

The only worthy men to intentionally crush on should be fictional and even those need vetting.

Having crushes is not something positive for women. The vast majority of men will ask out women they are interested in. The fact that a guy hasn't asked you out despite knowing you for some time implies he's not interested in you. Fantasising about the guy is hence pointless and will only lead to the guy using you for sex or attention, avoiding you, or gossiping about you. It will only bring pain if you are very obsessed with him. Most people don't fantasise about working at a company they never heard back from for ages after a job interview. I don't see why things for should be different for crushes.

Don't forget the guy you have a crush on may not even be single. Not every guy publicly posts about being taken on social media or wears a wedding ring so it can be hard to know for sure. You may unknowingly end up as "the other woman" when you take initiative in intensely flirting with a guy.

Are you talking about Leonardo Di Caprio?

In a kpop group. I recommend Block B's Jaehyo. Sweet, owns his own posh Gangnam restaurant, and fishes commercially, so while the group is on hiatus, he only does charity events.
