I am looking for a manga romance type, its the story of a girl who move in to a new house, and the house previous owner had passed away. But the owner became a ghost and just stay in the house with no memories. Then he met the girl and try to communicate with her. They fall in love. But then his "friend" met the girl and she know the girl can "see" him. His "friend" start to follow her and... I remember that his "friend" is the killer. He passed away in a party. My english is very bad, so sorry ;(. That's all i can remember. Please someone help me to find this manga. ╥﹏╥

Hi, in the past I read some chapters of yaoi manga where was boy with lion ears/tail and other boy with some kind of horse ears/tail..Can you please help me to find it?
(Sorry for my bad english)

This is a shoujo manga about a delinquent female lead and male lead. If I remember correctly they met for the first time in their first year of high school or middle school. The male lead was looking for the female lead cause he heard she was really strong so he wanted to challenge her but he only heard her name and didn’t know she was a girl. Stuff happens and they become very good friends. The ML falls in love with FL but she doesn’t notice. In one chapter, the FL skips school to attend her siblings parent conference I think cause they have absent parents. I also remember one chapter where she meets a rich young lady and helps her as she was being harassed, they switch uniforms for the day, the ML was really flustered when he saw her all lady like. I really want to find it again, thanks

So i don’t really remember this manga so good. The one thing I remember is that there is a new transfer student and meet his teacher. This teacher is kinda good looking (if I remembers this right) and the student is getting interested. But his classmates said that there is a game. So people is trying to get laid or trying to make this handsome teacher to fall in love with one of them. So the new student accepts this challenge and is trying his hardest but this teacher is kinda hard. At the end, the student starts to fall in love with the teacher but the teacher have no feelings what so ever. The student have given up and stops coming to the teacher’s room. When he stops coming, the teacher starts to realize he have feelings for the student or something like that. I don’t really remember. But in the end the they get together and are happy... i think...

So if anyone knows the name of this manga with my bad bad English summary. English isn’t my first language so I may have some wrong grammar here and there.
