After I Transmigrate into a Book, the Male Lead Forces Me to Love Him

[Two male leads + transmigrate into a book + possessive + coercive + uke-centered + ensemble cast + nation and family] After Lin Zigu died suddenly while reading, he discovered that he'd transmigrated into the frail prince from the story he'd been reading. He wasn't the protagonist, or even a supporting character, and he was destined to die of illness. The sky had fallen. Then he discovered that several of his friends had transmigrated too, to keep him company... Together, they decided to slack off in the world of the book. “Whatever, everyone dies eventually. Whether sooner or later, we're all going to die.” With that ideal in mind, they each settled into a life of idleness. None of them wanted to work hard. But as they watched one innocent person after another die a tragic death, their desire to live as layabouts gradually changed. They decided to protect this crumbling country by any means necessary. “When will the world finally be at peace without having to marry off princesses?” “The land is in turmoil and refugees are everywhere. The world is on the brink of chaos. If men can go to war, why can't women?” “Caught in the tide of the times, I can no longer see my own shadow. My name won't appear in the history books.” “I don't want to marry. If marriage will be the shackle of my whole life, then I'll never marry.” Let us build a high wall with our flesh and blood, and from then on, may all be well and safe!
