Serina and Mizukawa-sempai have been together for a wonderful year of firsts…and now their second summer vacation together is right around the corner. They’re ready for another summer of bliss together…but Sempai’s got to put his nose to the grindstone if he wants to get into a good school. As they spend less and less time together, Serina reminisces on how good it felt to fall in love with Mizukawa-sempai for the first time…and Higuchi-sempai tells her he likes her, too!
