I know Japanese a lil bit. Pm me k.. Hopefully i can help

I can try helping with Korean but I don't know if I'm a good teacher

Try talktomeinkorean.com
and download the HelloTalk app
You can only pick one language to learn on Hello talk so You can pick Japanese or Korean and Natives will teach you through a Language Exchange.
Also try conversationexchange.com It's like Hello talk but you get notified by email and then you can choose to skype or KakaoTalk~

Actually, i really want to learn Korean too :(

I really hope i could help you but I'm not that good at both.
Good luck honey.

I can help you with Korean if you want. I've been studying Korean for 5 years now. Sadly I can't help you with Japanese as I only been studying it for a year (and then needed to stop studying because of school ㅠ.ㅠ)

Why not trying to enroll for korean/hangul lesson.?
