Reading the comments, i think people are misunderstanding the "buddy buddy" relationship. This is just my take but seemed like ML is essentially making sure that he let's that POS ex know how good Nanase is doing now (and will probably will keep telling him that for years to come since they're 'friends' now) and how happy they're and all, so that he never forgets what he did to Nanase and what he lost doing it. Although I'd love for him to die a really painful death but since that isn't happening, this side of torture is nice too, since the author made it look like the ex had some sort of feelings for Nanase as well.
Having said that I still hope he just rots and dies like the villain in Vincenzo.
