After breaking up, I had relationship with my ex’s uncle-in-law - Chapter 54

So, acc to my approximate calculation, they have about a nine year age gap. [At the time of the fire incident(age): Pink haired white lotus=seven, Uncle=sixteen. And since Lin Yueyue and Mu Xiwei/Siwei (Weiwei if u wanna say her nickname) are supposedly the same age (In the panel, they looked like they’re the same age) and they are sisters, and idk where, but in ome chapter, there was smth lidat that was stressed) they should be about 9 years apart.
