if you love all their other music then that sunds like a group you might want to continue to follow
there's very few groups i stanned since their debut, because i normally need at least three or four comebacks to see if their quality is consistent or if it was just a huge burst at the beggining without the support to progress the group with good follow ups, or maybe the group does a 180 in style the next comeback.
Everglow is still a young group so i would't stan them yet personally even if i liked their music... but i also am not you and we may not have the same criteria for stanning. if stanning a new group does not have any issue for you and the only thing stopping you is one song, then i'd definetly stan, not every group is going to have every song right, and to have 1 stumble in their debut before finding their footing and firmly moving foreward is a LOT better then, like i said, a group with a great debut who is not as consitent down the road.
^rambling mess but it's tired so im not really able to edit it right now
