30-sai made Dotei Da to Mahotsukai ni Nareru rashii (2020)

They both deal with main characters who are past college age experiencing their first relationship. Both of the relationships are treated slowly and with care.

Both the Japanese series are adapted from a manga, are light-hearted and heart-warming and include a male main character that is secretly smitten with the other main character for years although the other main character thinks low of himself and doesn't expect that someone beautiful and succesful could have a crush on him.

For Mamoru Nekoyashiki, a doujinshi artist, the only thing that satisfies his need for approval is to sell his original BL manga at the popular Kabesa section (a section for popular doujinshi circles on the wall side of the venue) and be recognized by readers at the event. But then one day, something happens to him!

He meets Kazama Issei, a childhood friend he once had a crush on who is now a popular up-and-coming idol. Their lives in distant worlds should never have crossed paths, but you can't take your eyes off this story of two young men growing up in each other's presence!

Both are BL office romances between a director and an employee.

This work stars Akafuji Yuichiro, a popular and handsome actor, and Aoyagi Hajime, a former popular child actor who has the ability but is currently unremarkable. The story begins when they are chosen to play the double lead roles in the live-action adaptation of an extremely popular BL manga.

They start living together in order to prepare for the role and get publicity, but Akafuji has a curt attitude toward Aoyagi, and Aoyagi doesn't like Akafuji either.

However, there was a reason for his curt attitude. In reality, Akafuji was deeply in love with Aoyagi.

Akafuji tries his best to hide his feelings, and Aoyagi tries to get along with the other but mistakenly thinks that he hates him. The misunderstanding between the two leads to an unexpected slapstick comedy in this "Cohabitation Romantic Comedy".

The mother show of this spin-off. The side couple of Cherry Magic explores their story.

Adachi Kiyoshi is a regular salaryman who, at the age of 29, was still a virgin. On his 30th birthday, he suddenly finds himself acquiring a new power - the ability to read other people's minds whenever he touches them. Shocked and unnerved by this new ability, he struggles to cope.

That is, until one day he accidentally touches the handsome and popular fellow office-worker, Kurosawa Yuichi, only to find out that Kurosawa actually has secret romantic feelings for him. How will Adachi cope with this new revelation?

Both are workplace romance between a socially awkward guy and a popular guy! I think both dramas have pretty similiar scenes and interactions between main leads.
Story isn’t that similiar, but these dramas are both very cute and you might enjoy it :)

While still a virgin at 30, Adachi Kiyoshi gains a magical power – the ability to read other people's minds by touching them. At first, he’s overwhelmed by his new ability, and it’s not proving to be helpful to him. But that all changes when he accidentally touches Kurosawa Yuichi, whom he learns has romantic feelings for him.

Set at Shidou Gakuin, a boys' boarding school situated off the beaten track. In the second year at school, Takumi Hayama is allocated a room in a dorm to share with Giichi "Gii" Saki. Gii was brought up abroad and is the school idol with his exceptional academic performance, as well as his good looks. One day, Gii confesses to Takumi that he has been in love with him for some time. This unexpected truth of events unsettles Takumi, however, he comes to realize the true sensitivity of Gii

In both a very self-absorbed male protagonist encounter a very strange/magical event just before the age of 30. Then she has to-rethink and re-evaluate his thinking about himself and everyone around him.
Both are office dramas.
In then the self-absorbed person is surrounded by a cute junior who can't read well his surroundings... .and a senior who indulges him with work..and then surprises him with a lot of understanding.
His partner is a very capable person in his/her work and has a very beautiful face and understanding and gentle nature.
When they talk things out.. both couples are full with cuteness.

I recommend this both drama because , Male lead and Female lead
try to solve problem
In one drama explosion and another student murder/suicide
