Pursuing dream/career with mentor guidance

I like this kind of drama when:

• The MC starts from zero, preferably is an underdog and not genius/talented in the field
• Meets strict seniors/mentors and learn from them
• Makes a lot of beginner mistakes and thinking of stopping in the middle
• Grows at the end of drama
• Lesser romance involvement

The list contains all dramas in the genre, with those meeting above criteria the most are sorted higher.
