Idk how to feel

Seemed promising but after 10 chs, the pacing is going way too fast and nothing is really explained. Ch12 and we suddenly hear that MC actually has younger twin siblings? and how did she even find the MC?

Got through the first season then learned that the male lead is the older brother and not the younger one closer to her age. Idk stuff like this always makes me iffy about continuing a story. Age gaps are fine but when you've grown up together side by side like that is when I kind of draw the line lol. Not sure if i'll continue this or not.
