so in short it's just Ranto never dreams about his family, except on his birthday. But they stay the same while Ranto grows. His family apologized in the end that even though they know he's suffering they still want him to stay alive and have a birthday every year
there's a backstory on this, actually but I couldn't make it so I'm just gonna dump it here
english ver, how many times will Ranto raise his death flags? who knows....
