As the person who has read the novel, this is killing me all over again

Can you say where i can read the novel?? Please?

Use translation
And it's paid
Or js buy it from some site no free sources available for this one. You can read upto certain chapters tho but not the whole thing

Omg can you spoil what happens in the novel, do make a spoiler tag if you will huehue (๑•ㅂ•)و✧
