Jimon

Jimon is the slash ship between Jace Herondale and Simon Lewis from the Shadowhunters fandom.

Canon
Jace originally despised and looked down upon Simon. However, Jace did allow Simon to suck his blood while Simon was a vampire. Jace even admitted that he liked it and found it rather homoerotic. They eventually became friends/quest buddies.

Jace ended up paired off with Clary.
