Transmigrated to the Seventies, Busy Gathering Gossip

[Female-oriented, male protagonist's perspective + transmigrates into a book + doesn't go to the countryside + no System + communal courtyard]

Liang Jingze has no idea why transmigrating into a book happened to him, but since he's here, he may as well make the best of it. He's talented and clever, and he certainly won't end up as cannon fodder like he does in the book. Somehow, though, he accidentally becomes the foil to the heroine.
