no doubt is yg romantic but the thread is asking about senitmentalism and i'm not saying yg ain't sentimental at all i'm just saying that LCF just was more sentimentialisic than yg. even though LCF in his heart he loved Lin shiyin he believed that he could live without her love (to some extent he did if u include drinking and carving for ten years) however his friend was ill due to lovesickness and LCF believed that his friend would die if he couldn't get her love. even if it was a noble and brotherly act it is more sentimental because he knew he could still live on but his friend couldn't in his view.
not trying to disrespect YG as i i do believe that he loved xln more than his life but sentimenatlism goes to LCF in my opinion
