Sebastian is one of the twelve romanceable NPCs of Pelican Town, and his plotline is one that resonates deeply with me. He's a rebellious loner who might seem a little standoffish when you meet him at first, and a man you may have trouble even just running into considering he spends most of his days behind the screen, either working or gaming (Oh, and the occasional smoke break). But if you put in the effort to truly know him, to find out what his favorite gifts are or what topics he's into, you'll be met with a charming nerd who's more than happy to indulge you in some of his favorite hobbies...provided he has the energy to.
I deleted my past comments here before writing down what I had wanted to add...oof. But I do know that I wanted to add some things from the wiki, like his gift tastes and daily routine, and some other neat things that aren't mentioned (like the black earrings! I checked his beta sprites yesterday and compared them to his current one, those three black pixels are definitely meant to be an earring).
Also planned on adding my own personal headcanons, dialogue quirks, and all that.
