Both are botany horticulture related. Bio Homme has no romance and is fairly short, and revolves around how plants can help with mood therapy. However, both dramas feature cold and handsome MLs who are mostly married to their work. I was hoping one day there would be a full, longer drama projecting the themes of Bio Homme and I believe Romance of the Little Forest comes pretty close to it. Both are really nice watches if you like plants and nature.
