I have forgotten the names of each of these series.

1. A young girl transfers to a new school with no memories of her family and only a locket containing the picture of her parents and (she assumes) herself as a baby. She walks into her new class to see a girl who looks exactly like her and them together causes a tornado in the schoolroom. There is also a talent show involved, it is a very cutesy shoujo manga.

2. A manhwa where there are two best friends (sisters?) one who is always going on dates and the other who lives her love life vicariously through shoujo manga. Somehow she gets involved with a guy who at one point sees her so completely absorbed reading manga on a bus she doesn't realize he's sitting a foot away.

and

3. A manhwa where the main character is depressed and lonely, so she does a podcast about her which has a regular listener and faithful commenter who accidentally meets her in real life and doesn't tell her. He also has a really violent and rude friend.

Thanks.
