The passing of H. Mahidin HMS, who is the father of Firmansyah Mahidin Putra, also brought sadness to Chua Kotak. In the eyes of the owner of the full name Swasti Sabdastantri, his father-in-law was a loving figure, not only to his children but also to his sons-in-law and daughters-in-law.
That's why, the bassist of the Kotak band admitted that there are many memories stored in his mind with his father-in-law. Even, he always joked with his father-in-law whenever they met.
