Asking what love is in the world, it tells me that life and death are mutually beneficial. Traveling from the south to the north, how many times has the old wing been exposed to cold and heat?
In this world, what is good and evil, what is black and white, what is right and wrong? If it is wrong to love someone, then what justice is there in this world? If it's too difficult to love someone, it's just too rough. If it's easy to love someone, it's too boring.
If you wander around in this world all your life just because you yearn for one person, then you are not considered a great hero.
