A father's tireless dedication pays off, and he can become a truly COOL father to his daughters, both in terms of his father style image and as a father.

"Everyone waits for different things in life. Waiting for the day to go on a trip, putting money into savings every month; waiting for the day a loved one returns after graduation; being starving and waiting for your instant noodles to cook after pouring in hot water... It's difficult, yet exciting, and also requires patience... So then, what is it like... to wait for life itself?"
