Just as simple as the dad has a lover… the circle is cute and the fact that both are adapted from novel and has varieties of book there also its similarities i guess

Both of these dramas revolve around a couple getting into an accident. Afterwards, one of them is sent into the past and tries to stay away from their loved one in order to prevent the accident from happening.

The Sadness and Happiness are both centered around a zombie outbreak and having to survive. Both are action/thriller.
In both, the female lead is immune to the infectious zombie disease and both females make it out alive.
The Sadness is a Taiwanese movie while Happiness is a South Korean drama.

Note: isn't it funny how one is called sad and the other is called happy lol :) btw Happiness does have a good ending while the ending in The Sadness is left open ended.

TRIGGER WARNING: trigger warning for rape in The Sadness as the zombies there can't resist the urge to rape and murder (brutal and lots of gore). Happiness is a little better in the sense that it has romance even tho its slow burn.

Both are zombie apocalypse thriller/horror with disease outbreak and a life or death situation.
Both are movies.

Be aware of trigger warning for rape in The Sadness as the zombies there can't resist the urge to rape and murder (brutal and lots of gore). #Alive has a little bit on friendship/hint towards romance

Both MLs are deadly powerful beings but must obey the FL's commands as they are bounded by a spell related to their past life.

4. the supporting roles are cheerful and funny
5. a story treating the life of a specific category of society
