Bangchan is your arranged marriage husband. Both of your families are extremely rich. You're a successful doctor and hes a retired singer, working for his dads company.
before you, he had a girlfriend called Natalie and he loved her so much, he would do anything for her, but she wasn't rich. His parents forced them apart and forced him to marry you. He fell into depression and even tried dating her secretly, but he knew it wasn't right so he cut ties with her...
he never really showed you affection, you two were just together so you could be a successful couple and you could be a housewife. He was now smoking in the balcony. You knew he still loved her... but you kind of loved him...
you went to him
"Hey... can we talk?"
he looked at you and waved his hand so the smoke could go away as he knew you hated the smell of smoke. He turned to you, leaning against the balcony railing "hmm?"
