I'm glad they all vouch for Kim Dan,he's suffering from his grandma yk,me thinks. I hope Kim Dan does not have suicidal thoughts coz he lost all reason to continue life.
Spoiler: After the case settled,he left Woojung because he felt like a burden(a threat to be exact),left a note saying"I will live well" I'm crying. The puppy ran away but not long after he came back to Woojung.
Ahm,Jin is tempting.
