Summary
During the progress leading toward Miku's confession, the sisters – who all escape from their respective courses – were revealed to be helping Miku from behind the scene.

Story Impact

 * Ichika, Nino, Yotsuba, and Itsuki are revealed to help Miku in one way or another during Chapter 84.
 * Yotsuba's reasoning to help Miku is because she is the timid one and want everyone to be happy.
 * Ichika did meet with Fuutarou back in Elementary School Kyoto Trip. She played a card game with him during the night at the Inn.
 * One Young Nakano (other than Ichika) met with Fuutarou first, this is when they buy the charm (shown in Chapter 34).

Chapter Notes

 * Nino and Ichika both fake being sick to join Couse E. Itsuki and Yotsuba are also in Course E due to unknown reasons. This is another proof of how the sisters often have the same train of thought.
 * Ichika, Nino, Yotsuba, and Itsuki are revealed to cause the peculiar events surrounding Miku during Chapter 84. In order of events:
 * Ichika collided with Miku so she doesn't run away.
 * Ichika and Nino simultaneously promoted costume play from "House of Costumes" to prevent Miku from leaving.
 * Nino distracted Maeda and Takeda by leading them away from "House of Costumes" to the haunted house.
 * Meanwhile, Ichika disguised as Miku and talk with the "House of Costumes" clerk which resulted in the clerk pushing Miku to wear the dress.
 * Nino, through hugging Fuutarou, accidentally caused Miku to fall into the lake.
 * Itsuki, for some reason, brought a spare set of underwear that Miku can use (Chapter 79).
 * Ichika set a no-entry sign near Miku and Fuutarou's area, so they can have some private time together.
 * Yotsuba picked up Miku's bread (Chapter 80), however she forgot it at the hotel.
 * Nevertheless, Ichika brought Miku's bread with her and stealthily put it beside Miku (Chapter 84).
 * Callback to Chapter 1:
 * Yotsuba implies that initially, the black-hair Fuutarou was not Nino's type.
 * Nino knows that Ichika took interest in Fuutarou during their first encounter, presumably the one at the school when Ichika initiate the conversation.. However, Ichika stated that "it wasn't until that night..."
 * Ichika getting silent during that night in Chapter 25 is because she recognized Fuutarou as the boy she met years ago. Her reaction is never explicitly shown.
 * Ichika admitted that their meeting at the inn during the Elementary School Kyoto Trip is one of the factor that made Ichika like Fuutarou..
 * Yotsuba's reasoning to help Miku is because she is the timid one and wants everyone to be happy.
 * Ichika commented that their infighting is unnecessary.

Quote

 * "I... just want everyone to be happy." - Yotsuba Nakano
 * "Five years ago... Even if it was... Just for a short time... I'm sure it was because we shared that moment... That I came to love you." - Ichika Nakano
 * "Although Fuutarou-kun most likely isn't going to believe me anymore, but at the very least... That memory alone wasn't a lie." - Ichika Nakano
 * "Trying to get a leg up on each other and getting in each other's way...this fighting has all been completely meaningless. We're not enemies." - Ichika Nakano

Trivia

 * Yotsuba wears an outfit with diamond-shaped design, reflecting her order of birth.
 * The card game in page 4 does not have Heart number 6 and Heart number 8, a possible nod to Chapter 68 and romance.
 * This is the second time Nino hugs Fuutarou from behind, the first was when he picked her up with a motorbike in Chapter 59.
 * Ichika's somber reaction during Chapter 35 toward Fuutarou's question might also be a hint towards the revelation about her meeting 5 years ago with him.
