Douluo Dalu: A Fleeting Moment of Youth

In his first life, as a man, he lost everything because of one person.

In his second life, reborn as a woman, she meets the same man from her youth again, and once more gives herself up for him.

“If you love, then love. If you die, then die. Nothing else matters.”

(Both leads have lived previous lives, and are adults by actual age.)
