So if i understood this correctly, based on the replies, the drama didn't really show anything if the mother committed suicide or she was murdered. Most of your replies is based on assumption xD

If the FL's mom committed suicide, why is there a matchbox that contains the note that was found by the FL in the riverside?

Can anyone explain to me why did the killer killed the main lead and the mom of the female lead? I kind off don't understand that part

And the meaning behind the note in the match box
