Reincarnation

A little boy named Tita was handed over to the infamous Ice Witch. In her past life, she failed to raise him and he became cruel as a result. Now, a regular girl was reborn as her and she is determined to raise Tita right.
I think that it's cute seeing him grow up, from a cute boy to a rebellious teen. I'm scared that this will turn into a romance, I hope not.

Reborn as a noble, Jeanie Crowell is determined to never study and live a life of luxury
But she ends up working hard anyway lol
I love this character's personality, she's incredibly egotistic and short-tempered. But she's also very powerful so it's justified.

25-year old Kim Hyejung gets transmigrated as petty villain Latte Ectrie. She's incredibly quirky and weird, making all the male leads annoyed of her. Luckily, she has a special shield: the heroine.
I think it was really good but the ending was rushed

A girl who was treated unfairly all her life because of something she couldn't control. Hilise Inoedan died for the 7th time and refuses to be stepped over again for her 8th life. I dislike her whole family and I'm glad she's taking the reigns.

A noble with a name as cute as her demeanor, Sasha Tarte survives by acting as a pet for the nobles. While being pampered like a pet, she may also face the other aspects of one. Very cute manhwa !

a girl is reborn as an extra in a discontinued series so she works for the female lead as a maid

A girl who remembered her past life worked as a surgeon to atone for her past sins, only to die in a plane crash. She ends up back in her past life, retaining her medical skills, and works to be the greatest doctor!
I really like it, and I like the medical procedures applied

Patrizia was reborn after her family was wrongfully executed. Now, she is determined to take her sister's place as empress and make sure to never love the emperor
the art in season 2 improved drastically, it's so pretty o(≧▽≦)o

Calliope had her family die one by one by mysterious means. As she sung earnestly in the rain, a being was intrigued by her song and gave her another change at life.
Calliope is incredibly adorable and I love that she manages to attract a bunch of misfits
