Overall: this is what I would call a slice of life series, i.e. more true to life versus a romanticized version. Though I was put off at the beginning of the 1st episode with the flash forward and the first few episodes were especially slow going, I'm glad that I stuck with the series. Watched on Gagaoolala (also on iQIYI).

What I Liked
- some cute moments
- there were actually customers in the cafe at times and the cafe workers were actually working
- a character dreams different kdrama scenarios (I think one was Crash Landing On You) which was fun
- a character said that people who love each other should be able to marry
- the female friend wasn't a cliche evil wannabe girlfriend, though I don't approve of how she handled something
- representation (although I think the writers could have had a more realistic explanation/explained things better)
- Le's mom
- that nose ring, I think it's the first nose piercing I've ever seen in a BL, the hair was fun too
- the friendship between Le and Li

Room For Improvement
- I wish they portrayed the relationship between Li and Gwan differently. At first, I wasn't even sure what their relationship was. It didn't seem that they really even liked each other as friends with the way they treated one another.
- cliche "let me explain" then does not explain with side couple
- the main couple/side couple screen time was odd. Li and Gwan had an entire episode and then pretty much vanished.
- a bit choppy when they were in the forest the first time
- slow pacing
- I think the title "DNA Says Love You" should be "My DNA Says I Love You", I see it's listed as an alternate title but I wish this was the main title
- the pronouns appeared incorrect a few times, but I think this was a translation error (I didn't take off review stars for this)
