Lady Melissa didn't like the feeling of being uncomfortable whenever she had to even think of the idea of talking to someone privately, who wasn't someone she trusted.
Lady Melissa had a very short list of who she trusted in her life, and of course, her parents were at the top of the list.
As they should be, Justin was also a part of the list as he was her bodyguard, she wouldn't even ask her friend to give Justin to her if she didn't trust him.
Though it wasn't trust she saw in Justin in the first place, she just learnt to eventually trust Justin.
Well, it was hard not to trust him since he practically was with her the whole day or almost the whole day.
Lady Melissa ended up trusting him because of how much time they spent with each other, even if most of it was in silence.
