Similar vibes but Dear My Room is more focus on the female protagonist than in the romantic plot.
Also, the male protagonists are a bit similar, perhaps due to the long eyelashes eheh
If you liked Park Eun Bin's character Song Ji Won in Age of Youth, you'll like Dear My Room. The main character is basically the embodiment of her, a bit loopy at times.
A little bit similar in a way with hard-toil life of city chaos needs an motive to get ahead in a life of purpose with personal interests in art but awesome how it unfolds with other characters and their story.
