Holy sh** holy sh** hear me out gang
This phrase - " sua you promised that we will get married if we remain single until 30)
What if what if
This is a story from the side character pov ( our fml)
Because think about it there are stories like this which exists glorifying this because see if this was a story of ml having a one sided love for fml who is oblivious and said that as a fun way we all would have cheered for them and rooted for them calling yearning etc we would have never paid attention to the background or side characters who were used in that process but now when we are reading this we are feeling angry why? Because we are reading from that side character's pov which is opening a new perspective to us which we would/ normally turn a blind eye to
Anyways sua is fuc**** bi***
