Cherry Magic! Thirty Years of Virginity Can Make You a Wizard?!

SImilarities:

- Both are workplace romances between two men

- Both feature lots of one-sided pining and yearning while the other person remains utterly clueless

"Super Rich" isn't about both of them, nor a BL series. But both of them played here and still interact a lot with each other in this new drama.
I haven't watch it myself, but seeing the both of them in one drama again is enough of a reason to start watching this hahaha XD

office romance
in both drama both the title and the plot showcase an important focal age point for the main character.

If you liked the romantic plot set in the office of Cherry Magic then you will also like the romance in Roommates of Poongduck 304. The romance is very cute and funny as well.

Both are short BL dramas with an office setting. The MLs have contrasting personalities.
......................................

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.

They aren't per-sé alike but what makes me connect these two is how wholesome the couples are.
Life Senjou is about two boys finding love in their young years and continuing to love each other in a society that doesn't accept them. The focus here lies more on the story of their lives and has a realistic approach, whereas 30sai made Dotei is definitely more comedic and light-hearted.
Nevertheless, I truly love both of these and they are my favourite Japanese BL's this year. If you enjoy a sweet romance, these are your home.

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 dramas have similar humor and a cute couple even though the guys in Boy Next Door are not together.

Ootani and Tachibana have been inseparable since high school. Now that they're in college, they live together, they're happy and everything seems perfect. But their little world is disrupted when they meet an old high school friend, Yuki, who seems to have a crush on Tachibana, making Ootani feel jealous and insecure. Will Tachibana really choose him over a pretty girl?

Both dramas involve inner feelings being made aware for other people. In the case of Satorare everyone can hear one guys thoughts from a close distance and in the case of Cherry Magic! 1 person can hear everyones thoughts by touching them.

These dramas have very different setting (thai university - UWMA; office - ChM) but give off overall similar vibe:

Both are BL dramas with shy main lead and confident/perfect love interest who cares a lot about him.
The romance both dramas portray is very soft and cute.
Both dramas have fantasy element (reincarnation - UWMA; mind reading - ChM) and cute side-couple.

No hobbies, no friends, no lover. There are a lot of things that Kouki doesn’t have. The story begins when Kouki, an apathetic convenience store worker who struggles to find meaning in his daily life, is stabbed by a random thug. In his dying moments, he sees a beautiful angel with pure white wings.

Thinking he was being taken to the afterlife, he is surprised to wake up and find himself fully recovered. When he returns home, he discovers the same angel from before is already there. After learning that the angel has no memories and cannot fly, he takes pity on him and decides to let him stay with him for a while…

Both of them are cute, light-hearted romances with an office setting where one of the main characters is a late bloomer.

While 30sai focuses more on the BL romance in an office setting, Shujin-ko has multiple mains with one storyline being a BL also. I recommend both because they both have a refreshing take on BL that I can't really elaborate well without spoiling haha (especially Shujin-ko)
