Stockholm's Syndrome ?
nah, he never got love from his family has much as he did from his master, so it's def because he saw him as a authority figure, hard to say no to them
it's because he read his master's diary by accident and now knows how his master feels towards him, that diary kinda saved their miscommunication arc
He was never truly upset with his master he just thought his master only thought of him as a plaything he had no idea how he really felt till he read the journal then he high speeded their relationship because it's what he's always dreamed of.
I like the story and art, but why forgive him so quick? I wish MC tries to run away again, or hurts his master the way he hurt him...yk
