I don’t understand solo stans within the Tweny fandom

I have come across a lot of people (not on here) that only support Fifty Fifty because Chanelle (and occasionally Yewon) are in the group. All five girls are super talented and have wonderful chemistry but I do notice there are some “fans” who only want to support their R U Next picks. Please get to know Hana, Keena and Athena too
