Let's Stay Friends Forever

A year has passed. M is busy every day with his essay collection, but he still finds the time to attend his friend's funeral. In fact, M was the last person to speak to him before his passing.

After the funeral, M walks into BAR Lighthouse and finds a commotion. It seems everyone has some kind of plan to move on. Even Sawada is quitting his job to work for a TikToker. M cannot help but feel a little lonely.

Later on, at a bookstore, M gets a call from Kaoru, who is in a frenzy after a burst pipe floods BAR Lighthouse. Unlike their friends who are moving on with their lives, M and Kaoru both feel left behind. They realize this and make a certain promise to each other.

Finally, M finds the right way to finish his essays.
