I think Zichen's reactions when he finally learned the truth was just normal, yes, he hurt Chuntao but he was kept in the dark, he was not aware of it. As for the one night stand, he searched for her but he was left with no clue, his sister knew but was also asked by Chuntao to keep it from him. The kidnapping, yeah if he trully knows how to differentiate the twins he would notice but the twins often pull off their switch so is there any difference that time? What Yi said matters most to move forward cause they can't bring back the past. So I maybe biased to still like Zichen for Chuntao cause it's really not his fault to be kept in the dark.
