Pairing: Hibari Kyouya x Sawada Tsunayoshi
From [MangaHelpers](https://www.mangaupdates.com/groups.html?id=1011): If you're in despair, dial 111 and say "I want to be happy." A mysterious pair will show up that can grant you a single wish, the one thing you believe you need to be happy. On top of the wish, you must promise to become happy, or you must face deadly consequences at their hands. The first few stories involve a man who believes he just needs one more chance with his ex-girlfriend, and a woman who believes she'll be happy if a wealthy prince-like man marries her. [tethysdust]
