Sebastian lives with his mother, Robin, along with his step-dad Demetrius and half-sister Maru. Robin sometimes calls him Sebby. He feels that Maru is treated better than he is, and during Winter will talk about building a snow-goon that Demetrius demands he removes; he will then angrily question what his step-father's problem is.
Sebastian is good friends with Sam; the two can be found hanging out at Sam's house or at the Saloon playing pool. They also stand together at festivals, along with Abigail. It is hinted he may have a crush on Abigail, after Sam tells the player Sebastian really wanted Abigail to be their drummer "for some reason".
During the Flower Dance, if not dancing with the player, Sebastian dances with Abigail.
It is very helpful to try and get him to two or more hearts as soon as you can because otherwise he would be inaccessible as he does spend a lot of time closed in his room.
You find Sebastian working on his computer. When he finishes, he mentions that he's a programmer and is working on a project for a client. There's a notification on his computer, and Sebastian explains that it's Sam asking to hang out, but he would rather not go out. Robin enters his room moments later, telling him that Abigail was looking for him and will stop by later. Sebastian asks whether Robin told her that he was working, and Robin says yes, but Abigail decided that she would probably stop by anyway. Robin leaves the room, and Sebastian expresses his irritation that nobody takes his job seriously.
You see Sebastian working on a motorcycle in the garage at his house. He explains that it belongs to him and sometimes he goes for long rides alone far away from Stardew Valley. He suggests the possibility of you one day taking a ride with him, to which you agree or disagree.
Six Hearts
Enter Sebastian's room when he's there.
详情
Sebastian greets you, and invites you to play Solorian Chronicles: The Game with him. You play through a scenario, for which you'll be given a score between A and D. You're given a choice of archetype (which affects your score but has no effect on friendship):
"Wizard. A sharp mind is the most powerful blade of all."（不影响好感度）
To achieve a score of A: choose healer, go through the front door, attack then shield from the skeleton, go through the green glowy room, enter the hallway to your left, destroy the capsules and heal Sebastian's wizard. Sebastian is grateful, and he single-handedly defeats the boss.
Eight Hearts
Go to the beach on a rainy day between noon and 11pm.
详情
Sebastian is standing on the boardwalk. He's surprised to see you outside in the rain. He says he's anxious around other people, but he doesn't feel that way when he's with you. He takes out an umbrella and motions you to stand under it with him.
Sebastian is outside his house. He says he was about to go for a ride on his motorcycle. You join him for a ride, and he brings you to a place he often goes by himself to think about his life while enjoying a view of the city.
If your character is female, he mentions that he doesn't normally bring girls to this place. Otherwise, he admits that he's never felt this way about other guys, but that you're different.
He pulls on his cigarette a few times, and then asks what you think of the city. You have three options, one of which is telling him to quit smoking. Choosing this one causes Sebastian to be briefly annoyed; he says you sound like his mom, then admits that it's a bad habit and he'll try to stop.
He confesses his true feelings for you, and you embrace under the full moon.
Marriage
Sebastian's room.
Give Sebastian a Mermaid's Pendant to begin your Engagement & Marriage.
Details
After giving Sebastian a Mermaid's Pendant, he is very shocked upon your proposal. He tells you he will set everything up and the ceremony will be in 3 Days. He wears a purple suit, matching his hair color.
Sebastian's addition room on the farmhouse has a similar design to his room at his parents' house - there's a small table, couch and computer. He'll also set up a small area behind the farmhouse for his motorcycle, and sometimes go there to work on it.
