You can see this from two ways.
1. Papa is in the wrong. He has no right to violate her privacy and the right to love whoever she wants and be friends with whoever she wants.
2. Papa was just protecting Tia. Their family serves the royal family and Tia is engaged to the prince. He doesn't know about her past life. But he does know that people will form rumors about daughter constantly sending letters to another man, friend or not. What people will see is another man not friend. Those rumors will hurt her reputation and most importantly her. Which is what her father is trying to prevent.
Also, don't get me wrong. The dad was in the wrong. He should at least tell her the situation and what he's thinking. And I love Allen but he's kinda yan so protecting her isn't a bad idea lol









Sigh. Just big sigh, Ayaka. That was beyond dumb. You were taken to a hotel by some other dude, why are you saying you believe in him!? Dude literally told you AND your husband that y'all fucked. I don't care what your past is with that kamiyama dude why would you tell your husband, who's been saying he believes in you countless times, that you believe in another dude. Why defend him? Let his ass get beat. Tougo is your husband. Not the other dude.
