◍ Undertale / Classic ◍
• If you get to be his partner, man how lucky you are
• This skeleton got some real trust issues, and it's not easy to get together with him
• There's not really a big difference of how he acts towards his Partner and towards his friends
• Just will be more romantic and more protective, not to the point of being possessive though
• Get ready for his puns 24/7
• Man's not gonna stop making puns, no matter the situation
• He's not the type to show off his partner to everyone
• He's not easy to get jealous too, he knows that you love him dearly and that you won't betray him
• He loves to sleep on your stomach, on your lap, on your shoulder, basically just where he can sleep on as long as you're comfortable with it
• He especially loves it if he's sleeping on your lap with your arms around him
• He really respect your boundaries
• He's still lazy
• Please don't do anything bad to him and his friends and family, he will never trust anyone again if you do that :(_________________________________
