Serena y Seiya En la Preparatoria

Sailor Moon Cosmos, Serena, and Seiya reunite at the rooftop high school. Serena is writing a letter about the sunset postcard she received, unaware that it was from Seiya. Meanwhile, the Three Lights come to get some fresh air and rest. Seiya sees Serena, causing her to blush. Yaten snatches her writing, teasing her and criticizing her handwriting. She takes it back, admitting her handwriting is terrible, and he apologizes. Serena is drawn to seeing them again. Seiya, trying to remind her of what happened and knowing her name, asks her a question that touches her deeply, causing her to have a sharp headache. Suddenly, Haruka, angry and worried, tells them to leave Serena, reprimanding them for what they've done. Seiya replies that they didn't do anything and they leave. Serena tells Haruka to relax, explaining that they were just talking at the same time, and wonders why she felt so unwell.
