A lot of comedy and fluffy romance but very few fantasy elements, lots of unexplained events and plotholes. The female actors were good, the male actors were average to below average in terms of realistic portrayal of emotions, character growth, etc. (although all of them are eye-candy so 10/10 for that).
My biggest problem with the drama: the writing was simply lazy. It is the typical fantasy formula - male lead is some kind of an immortal creature (and old af), he meets a mortal girl and falls in love, only for them to be separated by some circumstances stripped of any logic, usually involving the male lead having to "keep his distance" from the female, in order to "protect her".
We get the typical cliches: female-male roommates, "the three musketeers" friend group, wrist grabbing, arm around the shoulder in "you're-my-woman "style, female tripping whenever the male lead is around (not even once did any of the other characters fall down, haha)., unrequited love, 20-year-old who has never been in a romantic relationship/ never kissed/ had sex, clueless about women male lead, etc, etc...

What I liked about the drama was that the female lead wasn't shy when it came to calling out people who disrespected her, and (thankfully) the male lead didn't have to interfere to "protect" her from the bullies.

Overall, it's your typical rom-com with a pinch of fantasy (to explain why total strangers from the opposite gender decide to live together). The soundtrack was so-so - neither awful nor memorable. The cinematography was of good quality.

I'd say it's the perfect drama for someone who's never watched the genre and isn't familiar with the tropes or for pre-teens/ teens, who want to see angsty strong females and their handsome boyfriends.
