NIKKE, after maxing out the favorability, all the Nikkis are not right

Green was enjoying a solo raid at home when he was kidnapped by the system into NIKKE's world and became the commander of the Nikkis.
After working so hard to increase the favorability, the system exploded.
"Even without the system, I can still achieve the goal of taking back the ground."
"Don't underestimate the bond between me and the Nikkis!"
Having said this, Green sneaked into Nikki's chat group.
Rapunzel: "Shared a picture of my brother's abs."
Nien: "This is the strongest firepower!❤"
Anis: "Damn it, there are more and more women trying to get close to the Commander lately! Rapunzel, this is all your fault!"
Marianne: "Commander! SUKI!"
Privati: "What kind of indecent group is this! I must confiscate these pictures immediately!"
Isabel: "My dear... Please tell me who is your girlfriend?"
Green: "Lavi, Nian, Anis, what I want is a bond, not to sit your nearly 200 kg bodies on my pelvis."
