From what I remember. Mew's mom was a servant/poor person that got with the dad but the mom found him another wife (Lookson's mom). When they're little kids, Lookson fell into the creek or something and almost drowned. Mom/grandma blamed it on Sai and got kicked out, she met Dodo here and always saw him as her hero. Her mom married another rich guy in another country where Willy is and they became friends. Fast forward to when they're grown and Sai comes back for revenge. Lookson is engaged to Jab's character but Sai kinda plays with him and so he breaks off the engagement. Lookson falls in love with Willy but Willy loves Mew. Mew however is confused and thinks that she loves Dodo so she kinda strings Willy along. Willy has major problems with his own family and Lookson is there for him while Mew is off with Dodo. He sleeps with Looksorn and then asks her to marry him. Sai gets jealous and Willy gives her one more chance to come to him. She blows it and rants and rave about Lookson taking everything away from her. Lookson overhears runs away in the boat. She crashes into the piers and dies cause she never learned how to swim very well. Everyone blames Sai for the sister's death but after awhile they forgive her and they're all just friends at the end.
