Raymon is suddenly flooded with vision of a dull, tired and malnourished Titania whispering sorry again and again. Then he notices how even though he hair way dry and her green eyes were tired, her eyes were clear when she said "I'm sorry that someone like me loves you' Raymon realises that her love for him is exhausted until noting is left. He asks her to use him but Titania declines saying she doesn't know what will happen if she acts like master instead of benefactor. Raymon stresses out that he swore his loyalty to her. She asks will that remain the same if she becomes the enemy of the Ducal family. Raymon disagrees at this saying she would never do something like that. Titania laughs and reminds him she has the emperor's blood flowing in her body.
✕Titania then smirks saying she is glad he didn't say a ridiculous lie like he would prioritise her over the Ducal family. She tells him he doesn't have to pretend to like her. When Raymon starts to disagree she cuts him off reminding how he held a sword at her throat when she mentioned the relic to him.
At this Raymon realises how on that day, when he pointed his sword at her she wasn't surprised at all. As if she knew he was someone would would even kill her for the Duke's family. Titania reminds him how they have a decent relationship now and asks him not to ruin it by treating her like a future duchess.
Raymon unable to stop himself asks her wasn't it the position she longed for. Titania flatly asks him if he'll give her the position of future duchess. Raymon feeling uneasy at her flat tone, replies with a yes. Titania laughs and asks him not to do that. Then she says she can understand where he is coming from. If there is an image that the princess-future duchess is someone who would sacrifice her life for Vivi, it would be a good thing for the Ducal family. But she says still that would not work. She straight up asks him to find someone to love and get married.
Looking at Raymon's surprised expression, Titania asks what will he do if Vivi, the sister he dearly loves entered a contractual relationship with someone for benefits. Raymon disagrees saying there would never be a situation like that for Vivi. Titania watching him go round and round in circles plainly tells him she plans to break the engagement. She didn't bring that up before because she didn't want to create any misunderstandings. Titania asks him to wait, but promises to break off the engagement since it is not something that can be done quickly.
Raymon felt repulsed at the thought of breaking off the engagement. Titania noticing his distress says the Duke cares for him in his own way, so he wouldn't have made Raymon sacrifice unconditionally for the family by tying him to Titania. Raymon asks why she is doing all this. Titania replies that she hates it when someone sacrifices themselves for her out of pity so she wants to end the engagement.
I like to post spoilers for the stories I find interesting because I don't have much time to read novel due to busy schedule
