Astro take on leading roles on To Be Continued, using their own debut names of course.
At the peak of their popularity, an all-male idol group — Cha Eun Woo, Moon Bin, Jin Jin, MJ, Yoon San Ha, and Rocky of ASTRO — is mysteriously transported back into time.

both FL has to marry defense officer to hide their identity and avoid assassinated by bad guy

1. They both take place for the most part in the kitchen.
2. The ML are both skillful Chefs that can be both arrogant and adorable.
3. FL end up working for the ML in their restaurant (and learning from him).
4. In both, the relationship between the lead starts off as a bit of love and hate; with the ML being very demanding in the kitchen and have little patience. As the show progresses and the ML becomes aware of his feeling, he becomes more patient and gentle with the FL.
5. They both have comedy, though Oh My Ghostess has a lot more.
6. There's a love triangle in both shows.

Big differences:
1. Oh My Ghostess has a supernatural element to it (having two main female leads pursuing the male lead, though one is a ghost). The show also has a crime element to it that gains strenght during the second half.

ALSB is a sweet and wonderful "variation" of Itazura Na Kiss and its many adaptations. This Chinese variation dedicates about 60% of the show to life in high school and 40% to life as college students and as young professionals, up until they decide to marry. What's special about this C-version is that the male lead shows interest in and cares about the main girl from the onset. At the beginning, he cares in his own quiet ways; then he slowly comes to terms with his feelings and to expressing them. The Thai adaptation "Kiss Me" was excellent. Both variations, the Taiwanese "Attention Love!" and the Japanese seasons 1 and 2 of "Good Morning Call" were great too, but ALSB does a better job in explaining the male lead's personality and decisions. Seriously, ALSB is a sweet show...

The both dramas deal with the realities of life such as death and trauma after an fatal accident. The main characters try to overcome the pains and family problems coming from their past. Throughout these two dramas flashbacks are shown about the past experiences of the main characters. The are both great in that they show that life goes on even after an traumatic or painful event and shows how people try to be happy after such events.

They both have a boss and employer relationship.
The male leads both have a traumatic past which the female leads will help them move on from or improve.
Main couples have similar chemistry/relationships.
Both are: thriller, comedy, mystery, and romance...

Both are thrillers and have mystery.
In both a person will be wrongfully accused.
The main couples are both cute and have good chemistry.
They both have a dash of comedy but have serious scenes as well.

both dramas are enacts about the daughters life. Actors are too good in father is strange compared to wang's family and also the screenplay.

Seoul, the present day. Ten-year-old Yeon-joo is picked up outside school by a man who says he knows her mother and is then driven to a flat where she is sexually abused. Six hours later, her mother, Yoon Young-nam, reports her disappearance to the police, who say it is too soon to launch a proper investigation. After being found dumped on the street in a suitcase, Yeon-joo is taken to a hospitalby Yoon and recovers; however, Yoon's ex-husband, TV celebrity dentist Dr. Lee, is not happy at the adverse publicity Yoon's action has generated. Yoon eventually persuades a busy detective, Ma, to take an interest in the case; he questions Yeon-joo in hospital but the child reveals little. Later, a female police officer questions her, with more success. Angry at the apparent slowness with which the police are treating the case, Yoon tracks down the child molester herself and confronts him at his flat. After a struggle and chase, the police arrive and take both of them in, though en route the child molester escapes. Yoon decides to take more radical action...

The similarities between these two dramas are of course, Rain. In both he plays characters that aren't purely good. They have ambiguous morals and do things that would land normal people in jail. The stories also have many twists and turns that might leave you dizzy if planning a binge watch.

Plus they're both crime thrillers.

They are similar because,
Firstly, both are story of a person who's work is serving his country.
Secondly, male lead fall in love and that girl helped him in his work.

Same goes to other Paragit Ruk series.
