Sian was On's ex-boyfriend, they were in a relationship together but the serious guy, he was an attention seeker he wants to steal On and he wants to do everything that will make On love him, he was desperate, so that's why Sian did become calm and depressed for what's happening, but Sian is really innocent but he can sometimes hide the pain, he is too feisty like his brother Kevin.
