I’m Yuna, married to Jin—he’s ten years older and has a teenage son, Asuka.Soon after our wedding, Asuka’s girlfriend, Karin, got pregnant.Their baby, Kira, was born, and we all started living together.
But Karin struggled after childbirth and left Kira with us.After their divorce, Asuka got custody—but as a high schooler, he couldn’t raise Kira.So in the end, I became the one raising him.



I care for Kira—feeding him, doing laundry, giving him baths—but part of me still feels detached.These should be Asuka’s responsibilities as Kira’s father, yet he does nothing. He’s completely left it all to me.
Sometimes I wonder… if I were gone, this household would fall apart. The word ruin comes to mind.And honestly, a part of me wants to leave—just once. I want them to realize how much I’ve done for free, how exhausting it’s been.
But I know I can’t. I don’t have the courage. Not even close.
