I really enjoyed this series, it offered an interesting medium to share what is such a painful experience.
Thought I would add the description from Lezhin, seeing as on here there is zero information available.
"Big See may seem simple on the surface, but at it’s core is a moving story about a man diagnosed with cancer. Readers witness the journey that unfolds in his subconscious as he battles cancer, and the emotional battle his loved ones find themselves embroiled in. After a successful launch in Japan, Big See is now available for the English audience. What is it like to live with the knowledge that your life on earth will soon come to an end?"
"The author has quite a few other comics which are unfortunately not translated, one of which is about characters who have to trace soldiers who have fled the army and is going to be made into a drama. "
Big See is one of my favorite webcomics and the summary of the other story sounds very interesting. It's such a shame that so many good stories never get translated simply because they're not smut/romance/BL etc. and therefor not profitable enough (and many fantranslators shy away from translating long stories, especially when it's pretty obvious that they're not going to be very popular).
AAAAAAAAAHHH WHEN WILL THIS UDPATE:(
