Even tough it's just 1 OVA episode, it's still so wholesome. There's no deep story about this episode, but a good story. It's not perfect, but I would definitely re-watch this again. Seeing Tsukasa feeling lonely because Nasa is at work and will be working for a while is cute. It gets more cuter when Nasa finally comes home and seeing her awake and smiling, waiting for him. It gets even more cuter seeing them sharing how much they miss each other and seeing their love grow stronger together, even though it was just a day being separated from each other. Even tough it's just1 OVA episode, it still made me smile.
