Recommendations

Both give a familiar vibe - to with a wealthy son and someone who works for a living. Highly recommend watching both shows

Both is school, youth and kinda comedy themed. And both show's about sportsmanship and teamwork. Also both their casts are so good looking ????

Why they are similar:
Famous male lead
FL suffering
Both ML has kinda disease (idk if we can call them disease) but of different types
Sleeping arrangements
Unlikely relationship
While my neighbour can't sleep is more of a cute type kakafukaka is more dark

In both Taiwanese dramas, the FL serves as a bodyguard. Each is a motherless children who has been heavily influenced by her fathers whose occupation is in a male-dominated world. Both FLs have supporting male friends who follow their fathers' orders and help them run interference as needed.

Differences
(1) FL context: TP involves a triad (I know obvious given the title) while SSB uses a security company lead by a former military man.
(2) FL role in love triangle: SSB has a clear 'nemesis' vying for the ML affection (2 females and 1 male) while TP has 2 men competing for her (2 males and 1 female)
(3) ML context: ML for TP is in show business while SSB ML is an automobile dealership CEO
(4) type of romantic story: SSB is more melodrama with lots of character development while TP is glitzy idol fare
(5) series length: TP = 6 30-40 minute episodes, SSB = 82 45-minute episodes

Ashes of Love is an epic angsty romance. Romance of Hua Rong is a comedy romance. They have different settings, but both have a fantasy martial arts / magic world.

I recommend them because they have very similar relationship vibe. They have strong male leads and impulsive female leads. The male leads decide early on that they will only and ever love the female leads, while the female leads can't seem to figure out how they feel. In AoL, it's because of the unfeeling pill, while in HR, she's just dense. Both shows have FL who betray/hurt the ML deeply, but the ML don't waver in their affections even so.

Love is Deep is a sweet romance. Both ML are physicians and the FL is the their patient.

Never Twice is similar to Pegasus Market in the comedy aspect, both aren't the usual comedies but different in a good way. They are even similar in the top acting and the good chemistry between the actors.
