There is actually 20 episodes. Each episode is only 2 minutes or less so it move super fast pace, but I still love the couple's development. It leave the viewers wanting season 2. I love how the princess is in charge, leading the inexperienced to love ML(a powerful martial artist/ her body guard) to her side. The couple is very good looking and the attraction/chemistry is really there. Their body language and communication between the eyes say everything. The storyline is not a new concept, but their chemistry made it worth it to watch. This couple also made many short clips together. Available in bilibili. Check those out too.
