Here we go:

After bringing Elizabeth home, Sleep became something of the past for Kōusei and Kaori as Elizabeth cried Day and night, when Not was when it was a asleep

Kōusei did return to High School despite being exhausted from lack of sleep, Kaori on the other hand looked completely different after a month with Elizabeth, Her hair looked rough, her eyes bloodshot red and her body shaking , she wasn't coping well with the babies screaming, she once passed out after the baby cried for 2 hours straight between 1-3AM, She also had to catch up with school work at home which she did as well, which meant she had no time for fun anymore, The Louds along with Kōusei tried to get her out of the house, but she wouldn't budge because she had to sought everything out.

Charlie wished he recieved more attention from his mother during this time, She kept giving attention to his baby sister Elizabeth and this started to make Charlie feel sad and neglected

Kōusei decided to take Charlie to places along with the Louds which Charlie enjoyed, Kōusei took him to some musical performances which he liked, but Kōusei could see that Charlie preferred watching Lynn Loud Jr playing sports which she getting really good at.

Then something happened

Kōusei returned from school early to hear a baby crying, he decided to go and comfort: Kaori, Elizabeth and Charlie

When he went into his and Kaoris room, he found Kaori just sitting on the floor, rocking

"Kaori, are you okay" said Kōusei worried

"What do I do, I can't think" said Kaori Who was teary eyed

"What do you mean" said Kōusei

"I don't know what to do, the baby keeps crying, My mind feels blank, please make it stop" said Kaori

Kōusei realised the hard truth of the situation, Kaori had suffered a mental breakdown from the stress of looking after Elizabeth as well as the school work, she looked a bit lost it and Kōusei had to hug her tightly all night to make sure she was okay.

The next morning Kōusei gave Elizabeth for the Louds to look after in order for Kaori to recover from the mental breakdown

Afterwards while everybody was out, Kaori slept for the whole day, Evan when everyone came back, They decided to leave Kaori alone to recover.

Kōusei decided to treat Charlie as he usually did, Evan though he was Charlie's step father, to Charlie's eyes Kōusei was like a superhero who spoiled him with treats and adventures whilst his mother was always too tired to do anything with him.
