Time travel and arranged marriges are my favourite drama tropes : ) There are a lot of good ones but they have a lot of epiosdes, i'll recommend shorter ones.
Princess at Large - 24 eps, about time travel and has a cute couple. Has Sheng Ying Hao who played the minister of defense in TROTAR :) Hate to love.
The Eternal Love - Two seasons, 24 eps each. About time travel and VERY similar romance between leads. Hate to love.
The Love by Hypnotic - Forced into a marriage, the FL often plays tricks like Qian Qian. Hate to love.
Unique Lady: Part 1 - Girl travels into a game where she meets a lot of nice men but she ends up in an arranged marriage with the one she hates but they eventually fall deeply in love.
The Romance of Hua Rong - Not time travel but involves a forced marriage between a sassy girl and a pirate. Similar romance . Hate to love.
All these dramas are quite similar to TROTAR, they have arranged marriages, hate to love, some have time travel and the romance is similar :)
