Chapter 1

Chapter 1 is the first chapter of the Umibe no Étranger manga.

Synopsis
Mio Chibana heads outside, where Shun Hashimoto notices him sitting on a bench facing the sea by himself. Learning Mio's name from his grandmother, Eri, who also lives with him, states that Shun is a pretty boy and feels Shun likes him.

They attempt to speak, which eventually culminates in Mio, joining Shun for dinner with his grandmother, Eri, and Suzu. Afterward, Mio shows Shun the noctiluca, the sea sparkle his mother liked. Kissing Shun, Mio informs him that he is leaving for an orphanage on the mainland tomorrow.

Three years later, as Shun considers Mio's lack of contact, Mio himself has returned. Feeling an adult now, Mio voices his feelings for Shun. However, the moment also includes Shun raising why Mio did not call and why he took so long to return.
