Him intentionally hurting his hand is a tad in the direction of a red flag... but not that bad yet. He shouldn't be harming himself to manipulate Luke for attention. BUT, we also have to remember that this is basically the first time Andrew has ever found someone that he truly loves and feels care from. He's been deprived of love and happiness and so Andrew probably wants to be coddled. I don't think he's the type to object to the MC having friends.
