After parting ways with Uzumaki Kushina, Uchiha Yin returned home.
As the third elder of the Uchiha clan, Uchiha Itachi's residence was naturally decent.
But the house felt a bit cold.
Uchiha Itachi, as the third elder, was busy and often away, and his wife had died on a mission, like Uchiha Yin's parents.
Only Uchiha Mikoto was left, but due to her strained relationship with Uchiha Yin, they rarely interacted.
And Uchiha Mikoto had been on a mission for the past few days, probably not yet returned, and even if she had, she'd likely be cold towards Uchiha Yin.
Of course, Uchiha Yin had tried to improve their relationship, but Uchiha Mikoto's prejudice against his previous self was too strong, and they barely communicated, so Uchiha Yin had given up for now.
So, Uchiha Yin considered going out to eat, as he had no interest in cooking for himself.
But as he entered the living room, his footsteps halted, and he asked strangely, "Mikoto, what are you doing?"
Uchiha Mikoto's face flashed with unease, then she forced a smile.
"Yin, you're back, I made dinner, let's eat together."
Uchiha Mikoto brought out the food from the kitchen, smiling.
But to Uchiha Yin, her smile seemed forced, with a hint of reluctance and resentment.
Is Mikoto sick? Or am I under a genjutsu? Or does she need something from me?
Uchiha Yin thought, puzzled.
Or did she poison the food? Trying to kill me?
Uchiha Yin knew Uchiha Mikoto's attitude towards him very well.
Since his transmigration, Uchiha Yin had seen Uchiha Mikoto at least ten times, but she had never shown him a friendly face, let alone spoken to him.
And Uchiha Yin wouldn't waste his efforts on someone so cold, doing things that were unappreciated.
But today, Uchiha Mikoto had actually cooked dinner? And waited for him to come back?
This... was even more unbelievable than Uzumaki Kushina's confession today!
Uchiha Yin looked like he had seen a ghost.
Seeing Uchiha Yin's expression, Uchiha Mikoto almost blasted him with a fireball jutsu.
But she held back her anger, forcing a smile, "Yin, eat first, I'll make a few more dishes."
Saying that, she ran back into the kitchen before Uchiha Yin could respond.
"Warning host, you have 3 hours left to complete the task, if you fail, the system will execute the failure penalty."
Hearing this voice, Uchiha Mikoto, already in the kitchen, gritted her teeth.
A week ago, a system called the 'Ultimate Brother-Complex System' had bound itself to Uchiha Mikoto.
This might also be the first bound system besides Uchiha Yin.
Similar to Tsunade's strongest support system, this system was bound to Uchiha Mikoto without her consent, and it even claimed to turn Uchiha Mikoto into the strongest brother-complex, one that must far surpass Itachi's.
Although she didn't know who Itachi was, Uchiha Mikoto still understood the meaning of brother-complex.
Brother-complex refers to someone who has feelings of "liking, doting, and protecting" towards their younger brother.
Is this a joke? Doesn't the system know the relationship between Uchiha Mikoto and Uchiha Yin? How can it ask me to become a brother-complex?
That guy has a terrible personality, is arrogant, looks down on others, and has a bad temper, which Uchiha Mikoto dislikes very much...
However, Uchiha Mikoto still gave in. She had resisted before, but after finding that she had lost all her chakra, she truly realized that what the system said was true. If she didn't complete the system's tasks, she would be forced to act inappropriately in front of Uchiha Yin.
Just thinking about acting inappropriately in front of Uchiha Yin made Uchiha Mikoto feel a sense of despair. So, within the system's deadline, Uchiha Mikoto started to complete the tasks.
"Side quest 1: As the strongest brother-complex, how can your relationship with your younger brother be so strained? Cook a big meal for Uchiha Yin and ask for his forgiveness for your past rudeness. Success: Fire-type chakra nature control proficiency +1. Failure: Forced to act inappropriately in front of Uchiha Yin."
