Even I'm also shock but I being realistic. No one can be forgiven so easy. Like old said, forgive but not forget. I just thinking, that's how is the best. If heesoo can't be safe & be rape at that time even the time right now apologize is not enough. So what Heesoo did to him, he had little mercy to him. He just give the choice to Chowon to always reflect to himself what he doing past & just move on when the right times is come. Im rooting Chowon for his love with Kyungsoo. He move on & become better person
He is Not selfish anymore. He try his best to love & live like normal family. He just feel left when Roselia always focused to Ein when they re three In one space. If Roselia can balance her attention maybe he will not feel be left there. But the style now is changing due to his high patient. U guys need give credit to him actually. Roselia is not clever to give the explaination but Claude be rational & not focused just one aspect do the rest. Actually, Ein still listen to his father most when his feeling is at climax. Roselia is a person to comfort him but who re always be there solve his conflict still his father.
