Harry Potter: Eclipse. - Chapter 64:

How massive must the wealth of a family that has been passed down for five thousand years be? Sometimes, you’ll never know how rich your family really is until you push your parents a bit! Only after inheriting his family’s five-thousand-year fortune did Zhang Menglong realize that the joy of the wealthy is so simple. Bank president, “Mr. Zhang, please, I beg you to deposit your money with our bank, and you can set the interest rate!” Huaxia’s top wealthy second generation, “Does the whole world belong to your family or what?” World’s richest person, “I feel like I am just a poor man!” European Royal Family, “Mr. Zhang, are you lacking a girlfriend? If you are, would you mind finding one? If not, would you mind one more? What do you think about our country’s princess?” Latter, Zhang Menglong found out that the college his parents left him was the most impressive thing. Actually, being a dean turned out to be even more joyful than being the world’s richest person!

Waking up, Kim Hajin finds himself in a familiar world but an unfamiliar body.

The protagonist, Winnie (文尼), confesses his love to his childhood friend—the princess he’s been secretly in love with for years—but is brutally rejected in public. His heart shatters, he’s humiliated and ridiculed, and he collapses unconscious. When he wakes up, he vaguely remembers his past life’s memories and realizes he has transmigrated into the world of an otome game he played before. At first, he’s thrilled, thinking, “Nice! I must have been reincarnated as a villainous side character who disrupts the protagonist’s romance, right?” But then… surprise! He’s not just the villain—he’s the “Saintess”!
