My Big Brother Is the Male Lead of an Infinite-Flow Story

My biological older brother is the male lead of an infinite-flow novel on a certain website. My sister-in-law is the female lead of a major novel on a certain other website, and she's even stronger than my brother. As for me, ordinary Lin Xiaoxian, there's not much to say. I was just dragged into an infinite-flow game by my brother and, from the start, managed to win over the seemingly pretty and obedient, but actually ruthless, top-level BOSS. Theme: Live beautifully through both good times and bad.
