Season one put you back in the summer of 2020, when a seventeenth birthday got swallowed by canceled tournaments and a school trip that never happened, and it made that small grief feel enormous. This is the show that understood the specific ache of watching your dazzling youth get quietly deleted, and then had a childhood friend nominate himself as boyfriend candidate like it was the most reasonable thing in the world. Round two returns to Mizuha and the four kids who grew up like family, and if you were paying attention, you already know the real reason to show up: Airu and Shugo. Those two carried the emotional weight last time while the central pairing kept fumbling it, and fans are still waiting for the boyfriend candidate's worst behavior to actually get reckoned with instead of glossed over. No spectacle here, just calm rooms, summer light, and the nostalgic hum of a hallway you swear you walked. Bring your grudges from season one. This one still owes you an answer.

Mizuho Nishino's teenage years have seen plenty of highs and lows, and as Christmas nears she wants to spend the holiday with all four of her childhood friends: Kizuki Hazawa, Shin Kashiwagi, Airu Izumi and Shuugo Hoshikawa. Kizuki moves first, saying he would rather spend it with her alone. After some hesitation, Mizuho opens up to him and names Kizuki her boyfriend. Word of the new couple travels fast, pushing Shin and Airu, who have struggled to face their own feelings for her, into the open. The close-knit group now meets a delicate situation it has never dealt with before, and this second season of the romantic drama asks whether the new relationship and the old friendships can both last.
