Song Tangjun's expression slightly changed, but his tone remained firm,
"I don't understand Yujin yet because I've never interacted with him. As long as we spend more time together, things will get better. Isn't that right, Yujin?"
Song Yujin did not say anything.
Song Ci was tired.
"Why are you ignoring the main point? Yujin is not interested in knowing you. He's rejected you as a father. Please stop disturbing us!"
Song Tangjun argued, "He's rejecting me only because we're not well-acquainted! I'm his only blood relative! His biological father!"
"That's not true. I'm Yujin's sister. We're blood relatives too."
Song Tangjun sneered, "Do you think those two roles are comparable?"
Song Yujin raised his head and said in a light tone, "My sister is all I need."
Song Tangjun was taken aback. His expression changed.
