Fourth-year undergrad Inukai Kousuke takes the stage, and at least momentarily gives Ayano a crisis in confidence, since he mentions how he holds his current lover in his arms twice a day and has spent over 227,000 yen on her.
Then we learn he’s talking about 2D girls in dating sims. When Yukimura tells Kousuke he has nothing to be ashamed of Ayano again begins to doubt whether she’s really in love.
When Kanade reaches out during a break, Ayano regales her with a story from her past. When she was in elementary school she was bullied for loving pillbugs. One day, while in the woods, she’s approached by a boy who not only knows what she’s up to, but voices his respect for it.
When she blames the pillbugs, he tells her she’s ostracized not for her hobby, but for having a negative “halo effect” due to her unkempt appearance and standoffish body language.
His call for her to keep her head up and move forward boldly “with beauty and dignity” is something she’s taken to heart, and indeed inspired her not only to pursue a career in science, but as Kanade says, became the cool, beautiful egghead she strove for.
Yet Ayano still feels she’s only partway there as long as she’s unsure of her love. Kanade figures out pretty quickly that the boy Ayano met and was so inspired by and smitted with thirteen years ago was none other than Yukimura. Naturally, the two don’t realize they met each other so long ago.
Rather than try to convince them then and there that they’re soulmates who should by rights be married already were it not for their scientific stubbornness and romantic cluelessness. Better to give them a chance to figure it out for themselves by going on a date.
Neither of them has any problem with this. The problem is, they don’t know the first thing about dates. Enter their three lab-mates, who offer three different versions of how their ideal date would go.
Kanade’s, naturally, involves the teacher she adored in high school, and quickly turns into a sugary shoujo scenario. Kousuke’s involves his tsundere 2D sweetheart, who looks an awful lot like his real-life childhood friend Ibarada. Ibarada’s involves a BL version in which Ayano is a dude with a very detailed backstory.
Eventually they settle on an amusement park date, and calculate the most efficient route to access all 22 attractions. It’s clear they’re overthinking things, but when it comes to actually asking the other out, Yukimura initially pooh-poohs the idea, before asking Ayano out, resulting in her most adorable reaction yet.
