Yosuga no Sora Temporada 1 Episódio 5

Haruka is standing near the girls locker room, overhearing Akiras and Kazuhas conversation. Haruka notices that Akira has been acting strange lately, and decides to talk to her alone at school the next morning. He sees the sad look on Akiras face and becomes worried, and wants to help Akira find her mothers pendant (after remembering her losing it as a child). They go in search for the pendant by a tree they would play by as kids, only to Harukas horror that the tree had been removed by a landslide. He attempts at digging around for it, but without any luck. The two go to Akiras to take a bath, and have a romantic moment together. From there, Haruka goes to the festival, and, after seeing Akira cry while dancing the sacred dance, rushes off to see what had happened.
