Enemys to Lovers

This story centers around the ship Obanai x Giyuu. Tanjiro and Nezuko have recently moved in with Giyuu. Meanwhile, Obanai's home has been flooded, leaving him unable to stay there for several weeks. In heavy rain, he goes to Giyuu's place and knocks on the door. Giyuu peers through the peephole but sees no one-so he doesn't open it. After more knocking, he checks the peephole again, still sees no one, and again doesn't open the door. After two more rounds of knocking, he no longer even goes to the door. On the fifth knock, he opens the door in annoyance and sees Obanai standing there. Will he let Obanai stay for a while, or not? Find out!
