I like TSJ due to his persistency chasing XY . There were times that he dishearten due to his scar all over his body, his leg limp. He thought that XY is beyond of everything that he will not able to match. He dare not to dream together with her, he know that XY can get the best man but he unable to let go of her. As long as he life to let go of her is like a death sentence for him. He willing to let go everything he has and follow her when:
1. he was nobody at Qing Shui Town (the physician),
2. she was a princess of hao ling (everyone adore her)
3. and even she was Chi Chen Daughter (when everyone hate/afraid to get close to).
though some ppl said TSJ too weak. But somehow, deep in my heart i root for XY and TSJ.
I know XL also love XY endlessly. He willing unconditionally to let the love poison bug inside her, save her even it cost 1 of his life and also his own life. But he will not able to let go everything and follow XY due to debt that he owe to his adoptive father. When XY asked him to let go everything, he like reluctant to let go.
*again this is my POV.
