Mostly cold and deep in talking about emotions and human nature. But he's actually selective, because he's warm, kind and servicial to Risa only
Withdrawn, terse, and emotionally restrained in ordinary conversations. Sebastián often speaks in short sentences and rarely explains what he is thinking. He can sound detached or indifferent, even when experiencing intense emotions. However, when discussing literature or writing, his vocabulary becomes unusually elaborate and poetic. His written expressions about Risa reveal his idealization, jealousy, obsession, and distorted understanding of love. He doesn't likes Agustín since he's too loud. But he does find Damián somehow appealing
To find someone who makes him feel understood, to maintain his connection with Risa, whom he becomes obsessively attached to, to avoid experiencing abandonment again, to impose his own idea of permanence on relationships.
Sebastián is a talented writer who uses language to express himself and manipulate others. He grew up isolated, experiencing bullying and emotional abuse within his family. His father is imprisoned, while his mother is emotionally abusive and frequently blames him for her problems. He confuses love with possession and believes that keeping someone forever is an act of devotion.
