Ep. 10: Haruka Enforces Eco-Friendly Rules While Mako-Chan Navigates Pajama Day

10

Haruka implements strict eco-friendly measures at home following high utility bills, restricting kotatsu use and washing dishes in cold water. This prompts Chiaki to adopt similar habits, though she falls ill and misses school. Her friends visit with gifts and prepare sukiyaki, while Kana invites Mako-Chan to dinner. The household observes Pajama Day, leaving Mako-Chan to protect his identity without Kana’s help. He doubts the importance of secrecy until seeing Haruka in formal attire, then urges everyone to buy sweets. Meanwhile, Chiaki asks Mako-Chan to sleep with her, adding to the day's events.
