Ah it was pretty brief but in an earlier chapter it shows Jasper’s father leaving their family due to a divorce and him blaming Jasper for it. Because the father left, the mom probably remarried and changed to his current last name.
The ending doesn’t explain why they forgot & why Jasper’s last name was Jang, I assume it was because of his parents divorcing later on but Jasper didn’t say anything about his last name being Jang when it was brought up.. maybe the ending was sorta rushed?? Idk I feel like it coulda been better
