I Promise To Return

I Promise To Return summary:

"Warning: Yaoi content: This manga contains materials that might not be suitable to children under 17. By proceeding, you are confirming that you are 17 or older."Yuqian may be the "greatest" guardian the Underworld has ever known, but he and his awesomeness can get a bit annoying. Naturally, he receives a task that can only be accomplished by the very best (and that sends him far away). He travels to the human world, on a hunt for a murderous demon as he helps Shuihua, a Daoist priest who's as pale as a ghost and who insists on pointing out how often Yuqian is wrong. Despite their bickering, can the dangers they face force them to rely on one another and show them how much they actually need each other?Liunian Zhan
