Yn and nezuko

(Next day sabito out the butterfly mansion)

Sabito pov:
I woke up by someone running down the hallway. I sit up I turn my head to the door and see Yn and nezuko. "Good morning Yn and nezuko I see y'all became friends already that's good". Yn grab nezuko hand and walk up to me. I look at them smiling and I noticed that nezuko was holding Yn's tail. Nezuko let go of Yn's tail and walk up to me. "Hi nezuko". I put my hand on her head. Nezuko face turn pink and hold out something. I look at and see it was a pink flowers crown. "Is this from me thank you nezuko". I let her put it on my head. "Thank you nezuko I love it". Nezuko eyes widened hug me. I hug her back and she pull back grabbing Yn's hand and ran off with her. "Even since Yn help nezuko control herself to not go crazy she been around Yn a lot good to see them getting along".

(Later on the Sun is going down so you and nezuko outside)

Giyuu pov:

Me Sabito and Makomo was sitting under a tree talking about something. "Giyuu every since you put that bamboo in Yn mouth she been really quite did you do something to it". Sabito ask me. I told him no and that she might be getting ues to it for being in her mouth. I look in front of me see someone running up to us it was Tanjilro who look really worried about something. "Have y'all seen nezuko I can't find her on where". We eyes widened after hearing that. We go up and start looking for her.

(Hours has pass)

still Giyuu pov:

It was now night and we still couldn't find her nowhere. I ask everyone have they seen nezuko they say no but one muichiro. I went to his room and knock on his door. No one came to the door. I open the a little and pick inside and see muichiro talking to someone. "I feel like I saw this girl before but don't know where". "You have she the demon that Kagaya told keep remember and she run up behind me and hug making everyone thinks she was going to attack me". "That voice is was Yn". I was getting ready open the but Yn said something. "Giyuu I know you there I can smell you". I smile and open the door and see her cover in flowers on her tail and Nezuko  and Muichiro who also have flowers on their hair's. "So nezuko have been with you all this time huh I guess she really like you". I hear someone behind turning around and see Tanjilro smile at what he see in front of him. Nezuko jump up and run to him. "Well I just I go too see you later Muichiro". Yn wave to muichiro and walk off with me follow her behind her. I walk outside and see Yn stand out there. I walk up to her and see the mark under her eyes is glowing. "even since I unlock my demon power this mark's being glowing for some reason and don't know why......I scared that lose control one day and kill someone even time I sleep it's feel like my father is right next to me watching me waiting for the perfect moment to come get me". I saw Yn trying not to cry. I pull her in for a hug." You know that Sabito, Makomo and me make sure that won't happen, You might be his daughter but you not evil like him, you wants to help everyone he wants to kill everyone so you NOTHING like him and if you do lose control WE be there for you no matter what". I feel her body going weak I look down and see her has fallen asleep. I pick her up and took her to sabito room. Sabito open the door and took her in putting her to bed. "You know she REALLY worried about her and her father". I said walking up to him. "I know, I made a promise to her telling her I take with me where I go to a mission so she can get stronger". I put my hand on his shoulder and told him to make sure not bad happened to him or yn and left them alone. "What so special about Yn that we don't know about to make Muzan go after her".
