Akachan ni Tensei Shita Hanashi

A salaryman (age 23) dies and meets a goddess, who laments his early passing and offers him a chance at reincarnation. No more than a few seconds later is he brought into the world once more as a newborn baby (age 0). At first, he thinks it's going to be great to have a jump-start on life. But it turns out that being a baby is harder than he expected? Originally posted on Twitter.
