is anyone interested in joining a small group chat ?

hello! i want to make a group chat, but i want to keep it small, i've noticed a lot of the group chats here often become like 100 + and i just wanna have one with like 20 max,
if anyone is interested in joining, please let me know!

i still don't know which app i'll use, that'll depend on the people who want to join, we can use line, discord, kakao, whatsapp,...

also, this is only for people over 18, preferably for people in their twenties, (i'm 26).
