Top Kokushibou x Bottom Muzan cuz yeah, and you can request

Kokushibo has always been a loyal servant to Kibutsuij, the demon lord. One day, however, Kokushibo feels.. warm, fuzzy, and.. in love? This is confusing for him.. He feels.. love for his leader.. How? How does a demon feel this sort of emotion? It's all so.. confusing.. How does Kibutsuji react? Does he feel the same way?
