I've seen many BL's so an office romance drama doesn't feel like anything new. However, the show offered a lot of cute moments with the two characters and made this a great short bl.

pros:
-age gap that doesn't feel unnatural
-good beginning
-the emotional scenes were really good
-good acting and camera angles

cons:
-uses a popular trop
-uses the same audio over and over again (but i still like the audio)
-only 5 episodes so they probably cut off a lot from the original story
-slightly rushed but it's not really anything to worry about

I hope for a season 2 cause I loved the characters. Also, this is a good bl if you want a quick watch.
