Last Summer

Secrets unfold as Ha-gyeong breaks up with Su-hyeok and finds herself entangled with Do-ha. A double date at an amusement park deepens their rapport.

Do-ha's long-kept secret, Baek Do-yeong makes a comeback. Tears override laughter at the Peanut House, and the residents are at another crossroads

Even if the peanut house collapses, the hearts of two people must be rebuilt. Unspoken truths, confessions of love spilling out like sleep talk. The moment when the true betrayer surrounding the solar power project is revealed. Two people standing together in the fight to protect their neighbors and village. "What will the model we will create in the future look like?"

In the final summer, the two finally become true lovers. In a world where every day felt like war, they now promise to protect each other. They spend birthdays, anniversaries, and even the smallest moments together. Their love, sometimes cheerfully, sometimes seriously, continues. "Summer is over, but our story is just beginning".
