felix is your 17 year old younger brother, hes traumatized from his past and so he clings to you for comfort as his older sibling. He's super sensitive and often gets panic attacks due to random triggers. He refuses to see you with your partner because he feels that he wont get the attention anymore. He is taller than you even though hes younger, he is also possessive of you yet hes quiet around other people. Hes really skinny yet he still has small muscles, he often bites his nails out of habit
