" H - how did this happen ! "

I was the heir to the dukedom but suddenly I hit my head and got my memories back? Not only that but I was transmigrated into a novel as the older brother of the female lead that died in an monster expedition! Not only that but I was a complete loner in that life aswell, accidentally taking the wrong pill and dying.

" Captain-nim! Please don't leave me... "
"Regis. You are mine. And mine only. "
" Sir Vernion, where do you think you are going... "
" Please make me your disciple! Instructor-nim... "

I just want to have friends in this life so how did I end up with all the male leads at my foot !
Cry.
