Watashi no Tadashi Oniichan (2021)

Both are mystery dramas. Wandering was of course a movie while WNTO is a mini drama. Both deal with inappropriate relationships, social misunderstandings and a pure, different type of love. If you've seen one, you'll like the other.

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 couples are traumatized and damaged from their past experiences and find healing and comfort in each other, despite guilt and shared trauma.

Similar themes of murder, trauma, and guilt. Both characters are damaged and find healing in each other, even though their relationship is unusual and messed up. Both are very engrossing Japanese dramas with a similar slightly unsettling tone.

Both dramas have the odd concept of the main couple pretending to be brother and sister and living together.

Both are Japanese dramas in which the FL has an unusually close relationship with her brother. In WNTO, her brother dies and she falls in love with someone pretending to be her brother, in ANAK, she discovers they're not blood related and they fall in love.

Similar dark vibes, and themes of murder and a couple against the world. ML desperately needs the FL and the FL is willing to do anything to save him.

Both take a different, deeper, maybe even slightly twisted look on love and what makes you a family. Both are also adaptations of mangas. The stories are completely different except for the fact that in both doramas the main pair are trying to lay low and hide from the authorities. If you enjoyed the overall story and vibe of the series you will like this...

This recommendation is outside the box..... but if you think along the lines that we get to define our relationships ourselves & those relationships don't always have to meet society's expectations or norm, this could be a solid choice. It's a bit weirds, but you may like it?

While one is dark and the other mostly fluffy, both are shorter length dramas, and have a sweet FL and a ML who likes to sleep on the FL's shoulder.

Difference plot but common themes of murder, loss of family, and a desperately needy couple who cling to each other when the world turns against them.

"When we grow up... We'll kill him together." Koichi, Taisuke, and Shizuna are three siblings whose parents had been brutally murdered when they were just in elementary school, and they vowed to avenge their death. Fourteen years later, their vengeful plan unravels countless new facts. A shocking revelation leads to an overwhelmingly emotional ending. What will become of the siblings who have lived their lives solely in reliance on their bond alone?

Both FLs are withdrawn and both MLs are deeply troubled after causing or thinking they caused someone's death. Both FLs are able to see past the surface of the ML to the good person they are underneath. Both leads cross paths unexpectently and slowly help each other heal.

Both dramas have the odd concept of the main couple pretending to be relatives (brother and sister vs. father and daughter) and living together. Both lies stem from helping/protecting the ML (letting him keep his business vs. protecting him from the law). Both dramas are quite short.
