Youkai Sharehouse (2020)

Both drama focus on the female lead and her adventutes surviving with the supernatural. Various stories of ghosts and supernatural beings. While Master's Sun focuses more on the romance, Yokai Sharehouse is more about found family and finding out where you belong in life, despite the adversities.

Both are comedies

The female lead starts off by being dumped by her cheating boyfriend.

The female lead is forced to live with strangers due to circumstances.

The female lead is unlucky/unpopular with guys before living with roommate(s).

Both are comedies

The female lead is forced to live with strangers due to circumstances and not having enough money to move out.

Both have ghosts and lessons in each episode or arc, both is funny but emotional. If you enjoyed the dynamics between Yiyong and the ghost so you are gonna enjoy these characters from japanese mythology helping a homeless girl!

Both main leads struggle with life and got dumped by their lovers, and find themselves moving into a house where the Yokai dwells. Both leads struggle between getting too close to the Yokai and risking losing their human lives becoming a Yokai themselves.

Yokai Sharehouse is about female lead, Sayounara Konbanwa is about male lead.
Yokai Sharehouse is about a human with a family relationship with the Yokai, Sayounara Konbanwa is about a human with a platonic relationship with the Yokai.

Both shows are cute to watch.

Similar story of a main lead who moved into a house where Yokai lives. Both have mix of comedy and seriousness. Although Kasuka na Kanojo is more serious as it focus more on high school dramas as it's about a teacher who struggles to reach out to his difficult students and unexpectedly receive help from a Yokai living in the same house who was a teacher herself.

Both are wacky dramas with chaotic female leads dealing with ghosts and the supernatural. Youkai Sharehouse is more funny while Tenma san ga Yuku is more scary.

Both have creepy horror vibes, but fun to watch.
Unpredictable plots.
Leads with special powers.
The romance is not fluffy at all.
(both plots are the kind only Jdramas can provide really)

Both the dramas are about youkais but in Yokai Ningen Bem they call themselves as plain monsters but in Youkai sharehouse the "monsters" are from Japanese mythical creatures. Both also involve a human befriending the monsters. Both of them are a good watch but in my opinion, Youkai sharehouse is funnier than Yokai Ningen Bem.

Both are cute dramas about a human living with a spirit.

Kanojo ga Joubutsu Dekinai Riyuu is about a guy living with a Yurei (Ghost).
Youkai Sharehouse is about a girl living with Youkai (Monsters).

They're both about how the complex relationships change them all for the better.

Both are lighthearted dramas about a girl living with someone unexpected.

Iine! Hikaru Genji-kun is about a girl living with someone from Japanese historical literature.
Youkai Sharehouse is about a girl living with monsters from Japanese folktales.

Good shows if you're interested in comedy and Japanese culture.
