Nice story telling for a one shot, takes your preconceived notion of what you think is happening and flips it. A phone is just a tool, what you do with it is up to you. @jak
My co-worker takes a break every day to video chat his daughters after school and ask them how their day went. It's that kind of warm feels that makes me think something like this manga can be true. Granted he shares custody with his ex and can only see them on week ends, but the tech lets him "see" them everyday.
The way this is set up so you'll go back to the first pages and see he's directly pointing his phone at everything rather than just being absorbed in it is pretty brilliant.
