Later, Wu came up with the idea to evacuate Republic City when Kuvira was going to attack. He was impressed about learning more of Mako's past. Mako ended up telling Wu about his past relationships with Korra and Asami and Wu willing listened to everything. Mako decided to work with Wu on self-defense. Mako decided to keep Wu safe by bringing him to the Sato estate. Wu ended up being kidnapped so Mako had to go rescue him along with Korra and Asami. Wu went to the bathroom but Mako refused to accompany him because he was tired of doing so. Mako was upset when he found out that Korra wrote to Asami but not him so Wu attempted to comfort him by saying that Korra also did not write to him. Later, Korra returned to Republic City so he joined her and Asami for lunch but was forced to bring Wu along. When the two were at a mall, Wu was depressed over having very little supporters and Mako finally tried to get him to get his act together. Wu later tried to comfort Mako after a quarrel with his brother Bolin over their conflicting political positions. Later, Mako attended Wu's coronation and witnessed Kuvira's direct opposition to him. Later, a bunch of Kuvira supporters started to throw pies at Wu so he picked Wu up and ran away from the Kuvira supporters. It turned out that Wu had personally asked for this because he felt like he could not live without Mako. Mako later learned from Lin that he was going to Ba Sing Se with Wu and stay as his bodyguard forever because President Raiko had signed off on the deal. Mako could not wait for Wu to leave so that he could go back to being a detective. Mako found Wu to be extremely annoying to the point where he had to bash his head against the wall for an hour each day. Mako had to always be with Wu and do everything with him. Wu had been moved to Republic for his coronation and the detective Mako was selected to be his bodyguard. Mako met Prince Wu when he was appointed as his bodyguard.
