I don't see the attraction. I don't know what I see between these 2. Maybe awareness of each other. As for the guilt, I have written too much on this already 🤣Viaan should man up and accept responsibility for his judgement and actions. He needs to stop pestering Katha to assuage his guilt.
my guess to why he feels guilty is that what happened goes against his own moral fibre. now even on this forum, people will have different ideas on whether it is moral or immoral to have one night stand. for some, it isn't a big deal while for others it is. based on what ehsaan said, viaan isn't the type to go for one night stand or casual relationships. so that may be another reason he feels enormous amount of guilt. in contrast, katha refuses to feel any guilt because she owns her decision to save her son.
