Chained Author's Transmigration

'I've always felt alone my whole life. I don't know if I like or if its because I’m used to it, but I know this' Being alone your whole life, changes you. Larian never had life an easy. Rejected by the people around him, he had legs crushed in an accident and lives in his Dad's place in his late 20s. He only had had one thing going for him. A novel that started as a diary for therapy, he pours his emotions into a fantasy world where Larian throws shit at his Main character. Transmigrated into his novel how is he going to survive all the odds he placed against himself? Author's note: Chain here has nothing to do with getting chained up(No BDSM). MC is not really an renowned author, but a person who was encouraged to write his feelings out like a patient dairy. The world he has written is a reflection of his own turmoil, so there is a lot of uncertainty in the area's MC has not written about.
