"Between" by Director Eri Hao, starring Marcus Chang, Esther Yeh, Sam Lin, Sean Lee, and Kelly Liao, is a different proposal of a typical storyline. I believe the Director's intentions were to focuses on very important life lessons across all 18 episodes. He shows us how decisions can affect people surrounding you one way or another. And that is always better to have a complete or panoramic view before you regret your decision taken.
Casts did an excellent job in each of their roles.
"Between" is not a typical love triangle story; this story is a lot more than that.
You have to work hard to conquer your dreams, but sometimes even when you plan your life in detail, things don't work as you planned, so you have to adapt to be a better version of yourself.
