I am looking for a oneshot manga about the girl saw the boy was troubled and suddenly pulled him inside the train. Then they agreed to pretend that they are going out because the boy is bothered by every confession.

The second is a manga oneshot about two highschool students; a girl and a boy who found themselves in the same place where they hang around often with a sensei. Then they are about to graduate soon and the girl is confused and doesnt know if she will become a good adult. Then they bought a present for their sensei as a christmas and parting gift. Then confessed to each other.

The third one is about ta girl who went to the future to know if her love life turn out well. Then she met her classmate, a boy. Then in the end of the chapter, she asked him how did he knew that she was from the past then the boy answered that her future self told him about it. Then she came back to her own time. It looks like that boy is her soul mate.

Fourth, is about having a strict father over protective to his princess preventing this guy to make a move on his daughter but the guy proved his love for the girl that is why he gained the trust and blessing of the father.

Fifth is the girl likes parasol/umbrella. She brings a different one everyday depending on her mood.
