Seth x Summer

Seth x Summer is the het ship between Seth Cohen and Summer Roberts from The O.C. fandom.

Canon
Presumably Seth and Summer meet as schoolmates since childhood. Seth falls in love with Summer with her upon hearing her read a poem that everyone believes she wrote to their class. Seth remains in love with Summer all his life and always looks at her remembering everything about her and feeling bad when she doesn't come to his Bar mitzvah.

Seth remains in love with Summer all his life, but never finds the courage to try to woo her, so when they reach adolescence, even though they attend the same high school, Summer doesn't even know about Seth's existence, let alone his feelings for her.

Season 1
The need comes immediately: Dawn Atwood's partner throws Ryan out of the house without her objecting too much and unable to find accommodation, the boy can do nothing but ask Sandy for help who decides to host him in her house for on the weekend, without asking Kirsten if she agrees.

Fanon
