Seth is a feline author found at the bar at Club Amorous and a Dateable character for the Player.

Seth is a green-and-white striped felid with pale blond hair and a pink nose. He wears an orange and black long-sleeve shirt with the sleeves rolled to elbow height, white trousers with a brown belt, and brown steel-toed riding boots. He also wears a pair of rectangular glasses low on his snout. To his side, he wears a brown messenger bag, where he likely keeps his writing materials.

Seth seems shy at first but he proves to be a very intelligent person throughout his storyline. He engages with the Player on an affectionate level and takes their suggestions for story ideas. He is also a scatterbrain and tends to lose or forget things throughout his interactions with the Player.

Several times, the Player describes Seth as "cute" or "adorable." Seth is probably the most tender of the current Dateable characters, and the relationship with him is partially focused on building an emotional connection with him, although it is more centered around the Player's assisting and encouraging his entrance into the world of writing and publishing, despite the Player knowing that this might pull the two apart.

Most of the Player's interactions with Seth are intellectual in nature; the two enter into aggressive verbal duels several times throughout his story line. Seth's writing is his life, and it's how he gets to know the Player in the first place, asking the Player questions about their opinions and sexual preferences.

Phone Number
The choices when talking to Seth don't seem to matter. You can be as pushy as you want, but in the end, as long as you don't leave him or decline going with him to the library, you will get his number.

First Date
Seth invites the Player to author Nik Kovac's book reading at a local library. The Player can secretly purchase an autographed book from the author and give it to Seth at the end of the date. After the reading, Seth and the Player go to a local coffee shop, where Seth describes his writing ideas and invites them to challenge him by giving him a genre and character type, around which he will write a story.

Second Date
After losing the Player's phone number and leading the player to believe he wasn't interested, Seth finally finds the Player through Coby at Club Amorous, showing off the rather hefty book he completed based on the Player's suggestions. Seth then spends the day in the Player's room and promises a future, fancy date at his apartment. At the library, the Player encourages Seth to approach Nik Kovac with his manuscript, which the author finds impressive and promises to hand off to his own agent for review.

Third Date
The Player goes to Seth's apartment for the promised fancy date. Seth, a novice at cooking, mistakenly prepared an excess of food. The two have sex, and the Player stays the night. The next morning, Seth receives a phone call from Nik Kovac's agent, and Seth and the Player set off for their office.

● Seth will always suggest the Player had told him to try romantic stories during the final scenes of his storyline, regardless of their actual choice.

● Seth is a virgin before meeting the Player (which is strange, given his being at Amorous, a place apparently known across the town for it being a hook-up club).

● However near the end of his route he has sex with the Player. The form of sex between the two is anal sex, a common form of sex in the homosexual community. Seth chooses to be penetrated, this and other behaviors imply that Seth has a submissive personality.

● Even though Seth has never been given flowers, he greatly approves of them.

● Seth's actually from a rich family, but moves constantly due to his parents' success.

● Despite Seth disliking wine, he enjoys the finest in vintage Champagnes such as Paul Masson's Californian Champagne inspired by the French.

● This is possibly a reference to the infamous commercial for said Californian champagne brand by the increasingly drunk-on-set Orson Welles in 1980.
