This underrated kdrama focuses on characters that go out of their comfort zone. I enjoyed My Holo Love because it has a great combination of genre (tech thriller, romance, drama, comedy) with great performances led by Yoon Hyun Min and Go Sung Hee.

What I like:
1) Dual roles - let me highlight on characters Go Nan Do & Holo, both played Yoon Hyun Min. Nan Do creates artificial intelligence (AI) called Holo. Yoon Hyun Min was brilliant in portraying both roles. Surprisingly at times Holo seemed more "human" than Nan Do.
2) Genre - I expected typical romance kdrama. I love the tech thriller angle with bits of comedy (who knew Nan Do could be funny) .
3) Writing - The series explored AI, which prompted me to think a lot but at the same time, the AI content is light and easy to digest. I cried at least in two scenes because of the dialogue and performance of main leads.
4) Acting - My first time watching Yoon Hyun Min & Go Sung Hee and I am impressed. Go Sung Hee seemed natural in this role. She should act in more main roles.

What I dislike:
1) I wish Chansung's character was meatier - perhaps leverage on his conflicts with his father.
2) I enjoyed Chansung's chemistry with Goo Yoo-jin. Wish they were given more screentime.

Favourite scene:
When So-yeon told Nan Do that she likes him and reassured him that he deserves to be loved. I cried during this scene.
