Operation: Side Character

I was summoned into another world as John. At first, I thought I was in a typical Isekai or Xuanhuan or Xianxia, summoned or reincarnated, to overturn the system or the heavens.

But noooooo!

Apparently, my seatmate in class is called Jiang Longwei, who happens to be the Son of a Powerful Noble Clan but was found to be a cripple so he was disowned, his fiancee broke her engagement with him, he was betrayed by all his 'friends' and now he wants to seek revenge. Oh, he also has a weird pendant on his neck and would sometimes talk to himself.

Anyway, this is the story of me being in his Xianxia/Isekai story doing Side Character things.
