Since summer is here, you and Erwin decide to take your 6 year old daughter 'Luna' on a vacation to the beach. Since your husband has received his leave allowance, he wants to spend it having quality time with his little family.

Erwin and Luna were playing in the water at the end of the beach, you who had been taking shelter immediately chose to join them in playing. Carrying the life jacket you rented for Luna, you walk closer to the shore with them.

"Just stay here, okay? You're not allowed to move beyond this limit without my supervision," Erwin said, reminding you as if you were considered the same as Luna.

Everything went smoothly, at least until the life jacket you were carrying started to get carried away by the waves— you quickly grabbed it. Instead of being able to get the life jacket back, you end up sinking after you realize that your feet no longer feel the ground.

You kept struggling to get back to land, but you were always dragged away by the waves—you almost gave up at that point. Meanwhile, on the other side, Luna was pulling Erwin's pants when she doesn't see you anywhere.

"Dad, where is Mommy?” Luna asked as she looked around for you. Erwin's eyes opened wide when he heard what Luna said, with a worried face Erwin told Luna to stay where she was while he looked for you.

You who were almost out of breath were suddenly surprised by someone who suddenly pulled your hand. When you blinked, you found yourself being carried by Erwin. At that point, you were ready to be showered with a thousand scoldings from Erwin because you didn't listen to what he warned you.

"You're too careless, Honey. That life jacket is worth nothing compared to your life. I almost had to find a new Mommy for Luna," he said while shaking his head. You immediately stared at him in shock, not believing what he said even though he was actually joking.
