Wesper

Wesper is the slash ship between Wylan Van Eck and Jesper Fahey from the Six of Crows fandom.

Six of Crows
Wylan and Jesper met during Kaz's ice breaking job, and bonded during that time. At the end of, Jesper became extremely distressed when he thought Wylan had died when the ship blew up. He was relieved to find Wylan alive, but was not happy that his face had been tailored by Nina in order to trick Wylan's father.

Crooked Kingdom
Jesper and Wylan liked each other from the start, and Jesper stated that he had wanted to kiss Wylan, since he had seen him in "that gruesome tannery". At some point, after Jesper gets in a big fight with his father after he confesses as to what he's doing, and since Wylan got tailored by Nina to look like Kuwei, Jesper accidentally kisses Kuwei. Wylan walks in to tell them about a meeting and sees them kissing, and is obviously hurt, but says nothing. During the meeting, Wylan blows up saying that it does matter that his face was changed and he wants it tailored back, hinting that he likes Jesper. After the meeting, Jesper talks to Wylan and says there is nothing going on between him and Kuwei. He gives Wylan a portrait of him (made by Maria Hendriks) for when he'll get tailored by Genya Safin. After it's done, Wylan has his face back. Near the end, they kiss.
