Both have college storylines but Boys Be Brave is the best out of the two. Blossom Campus lacks plot and character development and the actors need to polish their skills. It was underwhelming, to say the least. Boys Be Brave has better context to the plot and the actors do a good job with their characters. Even the second leads have great chemistry. If you're seeking a university storyline Boys Be Brave would be a great short watch. It has a similar time length for each episode just as Blossom Campus and overall 8 episodes.
Focus on only the main leads. No side drama. Similar plotline though this one's characters are younger. One lead has a love for cooking for the other. Short 6 episode drama just like OFC.
It is also a short BL like New Employee. And has a simple story line. The cast does a good job and the plot is heartwarming and cute.
