Overall, Girlfriend is a better version of WIL2

HPL focused on art, romance, and family with a bit of corporate politics. AIL focused on art, romance, and corporate politics with a bit of family drama.

I feel the HPL characters were almost lifted from AIL.

Male leads were painters who lived in the US, they both had to stop painting, went back to their home countries, and became gallery directors. They found their way back to painting with help from the female leads.

Female leads were art students and became curators.

Main leads shared a past, although at different times in their lives.

Second male leads were both athletes.

Second female lead (there were 2 SFLs in AIL) met the male leads in the US, and claimed to have known and supported them when they were at their worst.

Hello Again is a fresher take on Refresh Man.

* set in Taiwan
* high school classmates turned to colleagues
* male lead is the company head
* female lead was top student but turned out not-so-great and needs to be nudged by male lead to succeed
* the work both has to do with boosting sales

Put Your Head on my Shoulder is the youthful, perky, cuter version of Because This is My First Life. Both dramas have similar elements (but different circumstances, mainly because BTIMFL couple are adults).

1. Cohabitation
2. A contract
3. Intellectual male lead who never treated the female lead badly
4. Cute female lead
5. Drinking beer while watching TV
6. Leads were away from each other for a while
7. Third party FL who is not annoying
8. A cat
