Pffttt... the one with constant on the bottom of the line distribution?? Yeah they really APPRECIATED her vocal 🤭
Leeseo is vital to Ive, she will not be on the constant top 3 in their line distribution if she is not. I'm never saying that Eunchae is not important in Lsf lol, Im just saying that she is really weak outside of her maknae title. In year or two people will get tired of it and started questioning what else she good at outside of being a goofy maknae.
I think you may not be objective in your assessment. A particular maknae was last and got only 6% in a recent online poll of the favorite 4th gen maknae with 229k+ votes, whilst another maknae got 59%. So this particular maknae is effectively in a "and friends" role in their group.
She was super cute on debut, but as young idols mature they get less cute, and sometimes they are lucky and get a lot prettier and sometimes not.
