The Large Summer Harvest Festival (S01E04)

I'm Yoshikawa Chinatsu, and I love, love, love Yui-senpai. I can't believe I just said that out loud. How embarrassing! Final exams have ended and summer vacations has begun... but with school out of session, I don't get to see Yui-senpai. Summer's boring! Is what I was thinking when I got an invitation from my Yui-senpai! I'm so happy. I want to swim in the ocean during the day and set off fireworks at night! Yui-senpai's swimsuit! Yui-senpai's yukata! Hooray, summer's great! (Crunchyroll)
