Both are reality shows where a group of actors bond together through various challenges, In Boy's Journey, the series they will be acting in (Pit Babe) has already been confirmed but they don't know their roles, and in DMD Friendship, they are trying to find their partner to star within an upcoming BL (Not yet announced)

Boys Journey is a reality show comprising the whole cast of Pit Babe. Filmed before the casting of the character, we see the cast bonding with each other through various activities, like sharing life stories and a military training camp.

In the last episode, they are given the roles they will play in Pit Babe.

'Kabe Koji' differs slightly as the lead is not in the same profession as his crush (idol & doujin artist), unlike 'BL Drama' where both leads are actors. However, there are many similarities between the lead's admiration/obsession with their respective crushes, including being secret fans of their famous crush, having a collection of their merch/shrine and a connection to said crush in their past.

They have a similar bubbly extrovert vs cold introvert dynamic, sprinkled with an inability to communicate well.

They also both have a similar style of Japanese comedy, which is silly but not too over-the-top. If you like one, I'm sure you will enjoy the other.

Two people feel an instant connection at first sight, with the love of a previous lifetime connecting them.
UWMA is a modern-day reincarnation/soulmates story and the two gradually remember their past connection throughout the series, whereas IFYLITA has the added element of time travel and living out their past meeting. Both have a very similar vibe and an unravelling mystery/family conflict to accompany the romance.

An emotionally immature main character suffers a trauma in the past that causes them to have trouble sleeping. Their love interest helps provide a comfort/solution for this problem which helps them bond.
The 'top' in each show is also a wealthy heir to a business.

Similarity:
- MC falls in love with ML at school/pre-fame and proceeds to obsess over them from a distance
- MC is awkward/does not understand normal social cues
- ML is a rising actor who is not very expressive with their emotions
- MC and ML don't communicate well leading to misunderstandings

Difference:
- My Beautiful Man is Japanese, while Be Mine Superstar is Thai

Both shows feature an office romance, in which the main couple have a Boss/employee relationship. In both shows the boss is the son of the company owner.

The main difference is that Poongduck 304 heavily features the main leads living together as part of their conflict, as well as being a Korean BL compared to Step by Step which is Thai.

The main difference is that Step By Step is Thai, while The New Employee is Korean.

Both are Japanese productions that feature the male lead becoming involved with another guy who is responsible for raising a child (sibling vs own child). 'Our Dining Table' is much more lighthearted, whilst 'His' is more realistic with the topic of child custody.

'His' is the sequel movie to the series 'His - Koisuru Tsumori Nante Nakatta', which focuses on how the main characters met during their youth, but the movie can be watched as a stand-alone.

Although they are different forms of art, dance vs singing, they are both Korean BLs that feature one lead pursuing their dream in their respective field. They both feature the main couple living together.

Another music-based Korean BL, in which one lead pursues his dream to become a singer and the other lead tries to make that dream happen. Both have great OSTs, similar vibes and feature the leads having to live with each other.
