They meet, but the ML doesn't recognize the MC and initially considers killing him. The MC also doesn't recognize the ML, so he speaks positively about the ML when they sit together sometimes, which confuses the ML since he doesn't know who this person is. In one scene, they encounter an enemies and see the MC's old body. You realize that ppl have been trying to recreate the MC's body to deceive and attempt to kill the ML. This is why the ML and those close to the MC get very angry if someone claims to be the MC, as they believe the MC is dead and that others are exploiting this fact.
I loved the manga and the setting of the story but now that I am reading the novel it's very frustrating to read. Everyone is absolutely self centred and just plain stupid. It's irritating to read.
