Dude, you're breaking my heart
Not because of your situation, but because of how you feel about it.
I don't know if it will make you feel any better, but for what it's worth I'm almost in the opposite end---I married young (at 24), have two kids, mortgage, etc, however almost all of my old friends my age (33) are single, living their live---trips to other countries, nights out, parties or whatever rocks their boat. They call me less and less, because every time they do, I can't go.. I'm not Asian, so I don't know your culture and the people around you, but what I would do if I were you is to travel, go to the weirdest and most unusual places around the world, do something you never dared to, make a bucket list and work on it. Sooner or later you'll find your other half, everybody does, most often in the most unexpected and unusual places. But what's the rush, really.. you're a guy, you've got a job and no ties for mortgage, no expensive car...so you can take a vacation, vacations, unpaid if it may be...enjoy your freedom, because once you settle down, you'll have responsibility, a BIG one. And before you know it, you'll be a grumpy old man preaching to your kids about things you didn't care yourself when you were younger, and you turned out just fine.
