My Personal Weatherman (2023)

Both portray a submissive-dominant, master/servant relationship. The leads from both shows are flawed individuals who are not great at communicating their feelings to each other.

Hiro's so stressed out at work that he can barely have proper meals or get some well-earned sleep. When he passes out on the sidewalk after yet another stressful day, an unfamiliar face calls out to him - apparently, they once promised to marry each other? What's Kai Fukaya's deal, and why is he so insistent on assuming the role of Hiro's fiancé?

Overall, the two are simple similar due to the fact that they both have a male lead who draws adult webtoons/ manga, and a male lead who is jealous.

i) both are Japanese
ii) involves weather (entirely different concept though)
Bokura no micro na shuumatsu(English tile : End of the world with you) would be an amazing series to watch if you like Taikan yoho.

Both have MLs who have known and liked the other for a long time. If you watch one, you'll be like.. "Wow." I'm getting similar vibes...

These two are Japanese dramas, and both have a very similar atmosphere that the film style brings.
Both are beautiful. I loved them from the first episode. Highly recommended.

In both the dramas, the main characters are introverted and authors of erotic manga and they are at the lowest point of their career. They have a female best friend who helps them with their manga as well as their feelings. The other main characters are celebrities who are loved by their fans and audience. How these two characters grow in their relationship and understand each other forms the story.

It´s spicy. 
Kind of the same vibe, like a cold top and a cute bottom.
Taikan Yoho is a story where the characters know each other longer, but they don´t know each other at the same time, if you know what I mean. their only connection? living together and having sex.
