Ibelin says if he didn't notice what's in front of him (her sickness) then he never cared in the first place, so there's no need to tell him, which turned out to be right.
Can you imagine? The maids, his younger brother, and his highness, the prince, noticed she was sick and ML didn't. He only cared about himself.
I feel like Michi is the only one who is in love in this relationship, she is head over heels for Youchi while Youchi is just going with the flow. That's why it's always Michi who is giving her all in this relationship. Youchi didn't fall out of love, he didn't love her at all from the start. He just felt comfortable around her.










And that's how Sarada was conceived... <3
