Even though the genre is different (Stove League is about sports drama, while Life is about medical drama), the environment that surrounding the male lead is similar. Both of the male leads show less emotions (NGM & JSW) and not welcomed by their colleagues when they first joined the company/team. Both of them excel in their field, and through conflict that happen within the story, the colleagues starts to help the male leads. Both of the male leads are also supported by female lead with 'humanism' view and have a brother with disability.
