Kakkou no Iinazuke - Episode 7 - Friend The End

Erika wrote "friend" in the sand for a social media post, but the surf erased it to match her pessimism.

Erika confided to Nagi that she uses her social media pictures to make a connection with a certain someone. Romantic dramas need to be dramatic. Sachi ran away from home to live with Nagi and Erika. She claimed to hate her father's snoring, but it became clear that she wanted to stay close to her brother and get closer to her new sister Erika.
