My crush wants to be my sugar daddy.

Chi Yuan liked someone and thought that one night of romance would be enough, but he never expected that one day this person would bring a contract to keep him as a mistress.
Jiang Haochen originally wanted to raise a well-behaved kitten to relieve his boredom, but he didn't expect the kitten to be so docile that he couldn't resist it.
Chi Yuan knew that being kept as a sugar daddy couldn't last forever, and that the contract would eventually end, so he treated every day as if it were his last.
Jiang Haochen is growing to like cats more and more, but the cats are too well-behaved and never ask for anything: "You've been so good today, is there anything you want?"
Chi Yuan: "Could... I have it one more time?"
When his contract expired, Chi Yuan hoped it could be renewed, but that was wishful thinking. He shamelessly persisted until the last day, then resignedly packed his things.
Jiang Haochen returned home the next day and asked, "Where's my cat? How am I supposed to live without it?"
