It’s the end of the term and time for Summer Break – or in Kaizaki’s case, more lessons and make-up exams. There’s talk of the future. Oga mentions taking a look at universities other than the one Aoba High is affiliated with. Kariu gets restless.
Spring is classically when a young man’s fancy turns to love, but in Oga’s case, it’s Summer, and not without a considerable push from his de facto best mate Kaizaki, who has denied and is apparently content to continue to deny himself romance, since none of his high school friends will remember him at the end of the year.
At an impromptu adult celebration (i.e., with beer), Yoake and An mock his academic troubles, but also want the skinny on the Oga + Kariu impasse. Yoake also lauds his ReLIFE time as a “one year, limited edition of youth” he’s not taking full advantage of.
Kaizaki simply groans at that, but the next day when he has Oga alone, he really presses him on who he likes. When he says “everyone”, he forces him to narrow it down based on certain criteria. Once those criteria enter Oga’s head, he visualizes who else but Kariu.
One hot Summer evening while Kaizaki and Oga are walking home proves to be the clincher as far as Oga realizing how he feels about Kariu. He spots her talking to a man in a suit who seems to be trying to get her into his car. Then she gets woozy and the man has to catch her.
This is very confusing and not at all okay for Oga, who springs out to get to the bottom of it. Turns out, the man is Kaizaki’s kohai from last week (small world!) who saw that Kariu had heat stroke and didn’t want to leave her alone.
Oga offers to take her home, and because of Kariu’s state of mind, she lets her sincere, grateful side show, which Oga remarks at flippantly and gets punched for. “We’re always like this,” Oga says with a laugh. “It’s fun!”
He has no idea how much Kariu’s heart skipped upon hearing that, but on their silent walk home and late into the night, all Oga can think about is wanting to hold her hand.
Officially in love with Kariu, like he always was without knowing it, Oga reports the revelation to Kaizaki, who is appropriately obnoxious, but also privately proud of both Oga and himself for giving him that little nudge (though Kaizaki’s kohai deserves a smidgen of credit too).
Yoake, An, and Hishiro join in the discussion of what the next steps should be, and when Oga mentions how much experience with girls Kaizaki’s had, Hishiro flashes her first forced smile in a while, clearly miffed by the implication (just as she was miffed her pleasant walk to school with Kaizaki was interrupted by An).
Oga rises above all the chatter and bickering and makes the decision to invite Kariu to the Summer Fireworks Festival, in a text that bowls her over and has her wondering if he sent it in error (though he invites her by name, so that’s impossible).
She reaches out to the other girls, who also got invites, and realizes Oga invited everyone. She laments getting worked up for nothing, but agrees to go anyway. Inviting everyone is “just like Oga”, after all.
By the way, I really loved the energetic song that was played before, during, and after the credits: “Summer Festival” by Whiteberry, a super catchy, boisterous ode to life and youth featuring vocals that are just the right amount of off-key. Interestingly, it was released as a single in 2000, when Kaizaki (28 in 2016) was only 12. I figure it’s a song from his MD collection…
