Now that he's back to his old self, Tommo wants to make sure that he doesn't go back to being a cold reaper. He wants to purify himself so that he won't be tempted to return to the cold state again. Tommo explains that he used to rely on feng to keep him warm when he was weak, but now that he has regained his strength, he can't rely on her anymore. He's confident that she'll help him. He also tells Tommo that he scored a perfect 142 on his exam the other day, and that's enough to convince him to give this message to feng. He plans to give it to her the next day.
