YES! I had the exact same thought! you and I have the same mind my friend ヽ(`Д´)ﾉ
I kinda want to read that story as well
I think........ it was shiwoo's brother ( whose name is still not mentioned so... ) Who time travelled five years ago and then Jun and the brother ( whose name might as well be myung ) fell in love and somehow he disappeared and then Jun time travelled here ..... Just a theory ╮(￣▽￣)╭
This is something I'd agree with. Myung and the brother meeting somewhere, then Jun and Shiwoo here in the present world. WHAT A CONCEPT.
What if shiwoo's brother is in another world together with Myung since Myung disappeared too. I think I'm gonna go with that. So that Jun don't have to go back to his world and be together with Shiwoo ever after.
