4. Go Ahead
When Zhang Xin Cheng cried bitterly inside his mother's salon saying how he actually only lived in his father's house for awhile because later his father had another son then he was thrown away for not being obediently entering a business college iirc so he should earn his own money to learn baking. And that he hated how his mother, who thrown him away when he's still a kid, now pretending to care and meddled with his cafe business even though she now has another son (the son of her friend who's serving her time in jail actually) that she took care on her own. And that everyone will just thrown him away and that no one love him anyway.
5. Ripe Town
When the serial killer confessed that he was actually the arsonist's previous best friend, not the house's relative/adopted heir. And that he saw the arsonist burned and killed people and that he wanted to avenge the dead relative as a repayment for the money for study (from the book contained gold he found inside the well iirc) and kindness he received then he asked the arsonist, "If you know I was there, will you kill me?," in which the arsonist anwered with yes. Then Bai Yu Fan saw both of them dead one after another and cried his eyes out.
Force of circumstances...
