And this is why this is more than just a story about romantic love. It’s also about platonic love and how it is just as important.
Aoki was starving for support, desperate for validation of his feelings. Hashimoto was the first one to share her support for him, even after he called himself weird again and literally put himself inside of a trash can.
But Akkun could tell that something was off with his friend and because he cared so much, driven by how important Aoki is to him and how much he values their friendship, he had to get to the bottom of it. Even with all the detective shenanigans, Akkun found out what was wrong, how he had played a role in it and immediately approached Aoki not only to apologize to his friend but to share his sincere support and remind him that, no matter who he likes, Aoki is still the same Aoki.
And that’s exactly what Aoki needed to hear - from a friend who loves him and supports him - separate from who he has romantic feelings for.
Because without the platonic love from both Hashimoto and Akkun, Aoki wouldn’t feel confident enough to try again with Ida for a chance at something other than friendship.
