'Romance is a Bonus Book' episode 5 will reveal why Eun-ho never told Dan-i he loves her

‘Romance is a Bonus Book’, the latest K-drama to be added to Netflix library, is quickly becoming one of our favorite shows. Thanks to a strong and aspirational female lead and a desperately lovesick male counterpart, this tvN drama makes for a great watch. In the four episodes that have been aired so far, we saw the various ways in which resourceful Dan-i (Lee Na-young) has been trying to stay afloat after her divorce, even as Eun-ho (Lee Jong-suk) learned of all the troubles she has been hiding from him.
Through the various flashbacks from different times in the lives of these two central characters, we learn that Eun-ho and Dan-i go way back, and have been in each other’s lives through their ups and downs. Eun-ho had a disdain for Dan-i’s ex-husband because he knew right from the beginning that he was selfish and would hurt her. Eun-ho wastes no time in expressing exactly how he felt about the man who broke her heart, especially after he finds out that he even lied about fleeing the country.
