Tbh, there may be some twist there.
Ren, in chapter 2, when she learned that Sui is a college student, remarked that Sui looked older than that, to which she answered "I hear that a lot" and "Guess I look older than I am".
It just may be idle banter and not mean anything, or Chekhov's gun that Sui is indeed older than she pretends to be and is the colleague's old flame she trains herself to seduce.
Also, on the cover page, there's the sentence, "The reason I fell in love, the reason I feel this way, it's all because of you, right?" which could then apply to at least 3 of the women.
