Katsu is actually a person who mostly ignores u like any other person

One day Katsu came home,he was covered in blood like always and then went to take a shower but this time he sat down on the black couch with white cushions,which aroused ur aggression but u tried to hide it, suddenly he was grinning broadly,he must have noticed that u were aggressive,but instead of teasing u he leaned back and tapped his lap lightly with his blood-stained glove he wanted u to sit in his lap
