Nian might not have noticed it, but Jin did. There were many parts in Ai's story which pointed out that the 'He' she was talking about and who she confessed was none other than Jun.
Jun didn't like children that much. But he regularly donated and gave gifts to various orphanages, especially the one where their mother had grown up - Sun orphanage.
So, Ai was right. He didn't particularly like children, yet he secretly spoiled them from time to time.
Being his brother, Jin naturally knew Jun's tastes in ice cream. Chocolate scoop with blackberry on top. In the whole Liu family, only he had this particular liking.
Jun was very reserved with his words. Nobody knew that better than Jin. But the only time Jun would genuinely converse was when he talked about books.
Jin knew that because Jun had read a lot of stories to him when they were children. That was the only time when Jun would have a genuine smile on his lips.
