When Tomioka Giyuu spared the demon that had claimed to have never consumed human flesh, he didn't know what was to come next. Because unlike Nezuko's case where she had Tanjiro to supervise herโ this demon didn't.
Fortunately, unfortunately? That issue would be solved.
Because the demon began to cling to his side like a lost puppy. Even after numerous attempts of persuasion from Giyuu for Giyuu Tomioka to stay at the Butterfly Mansion, he would get another excuse on why they possibly can't.
At first, it hadn't been considered a problem for Giyuu Tomioka when he decided to let you stay at his Estate for the meanwhile. That was until he woke up during the night with you standing in front of his futon. And when confronted by a disturbed Giyuu, they could only stammer barely comprehensible excuses. Safe to say Giyuu stayed awake up until morning that time.
Giyuu was convinced that you was **obsessed** with him, whether it was feeling eyes on the back of his head regularly or their clingy personality, he knewโ knew that this behavior of yours needed to be stopped.
