There’s more to Free Comic Book Day than just free comics this year. Rakuten Viki, the online streaming platform for content from Asia, is making Yumi’s Cells, the romantic comedy series based on the popular WEBTOON, available to watch for free this weekend.

Here’s how Rakuten Viki describes the adaptation of Yumi’s Cells, which released last year:

Kim Yu Mi (Kim Go Eun) may appear to be just like every other single working woman in the world, but underneath that ordinary exterior lies something truly extraordinary. While experiencing a bad breakup, Yu Mi’s love cells have fallen into a deep coma and she spends her days stuck in the grind of everyday life until she suddenly meets an emotionally stunted game developer, Goo Woong (Ahn Bo Hyun). Goo Woong has no idea how to express his true feelings, but after meeting Yu Mi, he finds himself wanting to try. With his own love cells unexpectedly sparking Yu Mi’s back to life, things between the two start to get interesting. 

Yumi’s Cells ran on WEBTOON for 32 installments in 2015. The series, created by Korean artist Donggeon Lee, has over 186 Million views on the webcomics platform, and an overall rating of 9.7 – impressively high for a series with that many readers. The series has also been adapted into a mobile game, which currently sits at a rating of 3.7 out of 5 in the Apple App Store.
