~하고는 하다 When you express that you do something "sometimes", you can use it :) It can be shorter , 하곤 하다

@김그린 thank you for sharing your opinion

I’m Korean. There isn’t mean ‘지곤’. It’s wrong. But i reckon this is ‘자곤’ - “꼭 함께 자곤 해” And ‘해’ is awkward. I think “꼭 함께 자곤 하자” So “Let’s sleep together”?!? Just my opinion. Sorry for my answer you don’t want Thank you
