Lolig's manga / #red string(3)

Satake Aoi, a university student, wakes up rolled in red string, the result of a promise granted by a god whose name I'm not even going to begin to spell out. Thus begins Satake's days as Mr. Popularity, a situation that isn't as much to his liking as he thought it would be when stonkered out of his gourd. Now he's got to pay up by becoming the god's bride.

College student Keiji possesses the dubious talent of being able to see the red string of fate. One day, he suddenly notices a red thread tied to his own finger! He is tickled pink on catching sight of it and immediately follows the thread, but the thread leads to his own kouhai called Hiro!!…"My soul mate is a guy!?"

Spin off of Akai Ito No Shikkou Yuuyo! This is about Kamisawa, the guy who knows how to cut the red strings of fate (and other strings). He’s contacted by a client named Hara to help him get rid of a stalker but Hara can’t get Kamisawa out of his head and decides to pursue him even though he’s warned that Kamisawa can’t fall for anyone.
