I used to get Jin and Jimin mixed up from BTS
and Youngk and Sungjin from Day6
Siyeon and Sua from Dreamcatcher still get me sometimes
I had a little bit of trouble with Bitsaeon and Narachan of M.O.N.T but that was more putting the name to the face, I could tell them apart I just couldn't tell you their names
Red Velvet's Yeri and Joy
GOT7's Jinyoung and Youngjae
EVERGLOW's Mia and Sihyeon
TWICE's Jihyo and Momo
*there are way more but i'm too lazy to list them all
Whenever I start learning members of a group, I feel like giving up because I can't tell them apart. When I finally find out who is who, I always ask myself how I thought they looked alike, because they don't at all lol. I think I got Jihyo and Momo mixed because of their big eyes tho.
This has to happen to every k-pop stan at least once
..usually nothing because it takes me hours to learn the names and by that time i usually know everyone clearly
other than that one time i just got into bts and mixed up J Hope and Hobi and Hoseok
when i first started stanning skz, i'd mix up hyunjin and seungmin. they don't even look alike
also, seulgi and wendy. again, they don't look alike.
also, i could never remember jungwoo's name. i knew his face, i knew he wasn't any of the other members, but his name just never came to me
