I recommend this both drama because , Male lead and Female lead
try to solve problem
In one drama explosion and another student murder/suicide

Both are about the growing romantic relationship between non blood related siblings (step vs. adopted). Both are set in school.

Both dramas have a theme of unconventional family, in Marmalade Boy they swap partners while in the other one they have partners of same sex.

Koishikawa Miki, a high school student, is told by her parents that they are getting a divorce and swapping partners with another couple. The other couple have a son called Yu, whom Miki becomes attracted to after moving in together.

Both movies are about step siblings romance. Understandably enough, the characters tried to suppress their feelings for their step siblings for different reasons which made their stories unique (we all know how step siblings romance is overused). I also like how the parents are very chill on both movies, although it’s kinda worrying (esp on Marmalade Boy), they are very supportive XD. Also, the male leads are popular vs second male leads who are always trying their best TT. Overall, Liar x Liar is fluffier and easier to watch, while Marlade Boy is kinda sweet and sour IMO.

"Newlyweds" Keiichi and Akira Hirose have moved to a new city. Keiichi, who works as an author, and Akira, who works with kindergartners, are hiding a big secret from the people around them.
