Twenty-One, in the Prime of Youth

Two lives, two cycles of reincarnation: In his first life, he was a top-tier professional game booster. But he trusted the wrong person, gave her everything, and was deceived by layer upon layer of lies from the woman he loved most. In this life, he hated himself for arriving before love. In his second life, he looked back on everything that had happened and realized that making sacrifices just to feel good about himself was both dangerous and foolish. He finally understood that you must love yourself before you can love someone else, and know someone's heart before choosing them. In life, everyone but yourself is a supporting character. The most important thing is to be the protagonist of your own life, keep your emotions steady, and be financially self-sufficient. Only then will you have the strength to love someone else.
