If you are looking for groups to look into I would recommend Seventeen, they are my favorite group. However, they are a fairly large group, so if you are looking for something a bit easier I would try TXT for a boy group and ITZY for a girl group. They are a lot smaller and they are newer so there is less to learn about them. TXT is also having a comeback tomorrow, but that's just me being excited for that. You may or may not like these groups it depends on your concept and style preference. If you want to talk more about this feel free to private message me!
