Lol it was basically the same as the manhwa. You can find the translation of the chapter under "3rd Book Spoilers" and "the deed" here: https://forum.novelupdates.com/threads/the-villainess-lives-twice-%EC%95%85%EB%85%80%EB%8A%94-%EB%91%90-%EB%B2%88-%EC%82%B0%EB%8B%A4.106143/
They kissed in bed and then woke up the next morning ^^; the second time they sleep together will be a long time from now.
Lol "the deed" refers to them sleeping together. The manhwa covers it the same way the novel does--they omit the details and just wake up the next day ^^; Cedric and Tia do like each other though. We also learn that Cedric regains his memory bit by bit. We get a hint of that from ch. 72 of the manhwa too when he says "I should have done this a long time ago" as well as in ch. 73--while Tia is sleeping, he whispers "You are the first and last woman I thought I wanted. Even before and after. Even if another life comes, it will be the same."
