I kinda feel bad for both of them. Even if it turns out that Farsei and Hanseng are the same soul, Hanseng has the right to feel upset for having the current affection his siblings have for him as Farsei. He had no memories as Farsei after all.
i get u. butttt the only reason they adored farsei because he was in hanseng's body. they just started to truly like farsei after a while. they sticked and endured the stubborness of farsei at first because he was 'hanseng'.
