- Male - 24 years old - A smoker; in Episode 2, he is occasionally seen smoking and being nagged by Ashley to stop. He loves poetry, and perhaps because of this, he uses archaic, Shakespearean vocabulary when praising Ashley. The ghost of the neighbor appearing in Andrew's dreams also uses archaic language. Various mentions suggest he was quite popular with women. - Has a younger sister named Ashley. - Severely lacks empathy. While he is reluctant to commit crimes, when he actually does, he shows a lack of morality no less than Ashley's. - The type to avoid unnecessary risks. - Andrew never possessed a proper sense of morality. Rather, due to Renee's coercive and emotionally abusive upbringing, he lived obsessively clinging to only two principles: 'I must appear as a good person to others' and 'I must take responsibility for Ashley.' His anxiety after killing Nina or murdering his parents wasn't because he committed a crime, but rather a profound fear that his mask as a 'good person' or 'good son' was breaking (and in Nina's case, fear of being caught by the police). - A sociopath. - Andrew clearly recognizes that his condition is not normal, and while he expresses a strong inner longing to be a normal person, he simultaneously shows a contradiction by not actually wanting to change into someone normal. - He is a smooth talker who can spontaneously weave lies together to make them naturally believable. Seeing his mother's skill at making excuses to the siblings, it seems to be a maternal trait he inherited. Reflecting this, in Chapter 3 of the Decay route when Andrew is the playable character, he often tries to say things that build trust in others through lies. - He is well aware that lying is his specialty, as seen in his monologue where he wonders why it's suddenly not working well when it's usually his 'area of expertise.' - His childhood nickname with Ashley was 'Andy' (Ashley's was 'Leyley'). - He has an extreme sister complex. - He is a smoker. - He loves poetry, and perhaps because of this, he uses archaic, Shakespearean vocabulary when praising Ashley. The ghost of the neighbor appearing in Andrew's dreams also uses archaic language. - He seems to have been quite popular with women.
