일본어, 중국어랑 한국어 같이 배워도 괜찮을까요?

Hello! I've been living in Korea for about a year now, and I'm a foreigner who really enjoys learning languages. These days, I'm learning Korean at an intermediate level in Seoul, but I'm also considering learning Japanese and Chinese at the same time. Is there anyone who has experience learning Korean, Japanese, and Chinese simultaneously? I'm worried that they might be confusing since these three languages have many similarities. I'm concerned that learning Korean might be hindered. I'm currently attending a Korean language academy in Gangnam, but it's not easy to find Japanese or Chinese language academies. I tried looking on apps like Zigbang, but I'm not sure where to start. Could you recommend any easy ways to learn Japanese or Chinese in Korea or good language academies? Any advice would be appreciated! Thank you so much for sharing your experiences!
