Guys do I have to read the other story first before I start this one?

nope!

Yess. They're actually stand alone but characters from first story will also be appearing here and the relationship between them is also gonna be prominent especially the friendship

i read this one before the other one and i didn't have any complications about it, so its okay if you do! still, id recommend you to read it first (just to have a little more of context)
