Honestly Jeehan is acting like a manipulative asshole. He totally railroads anything she wants to do with his way. He totally refused to let her handle the matter with his brother in any way and stole her phone which was incredibly manipulative and immature. He had no right to forbid her from talking to her friend and explaining what was happening. He did that purely to spite his brother and probably irreparably damaged her friendship with him.
We keep seeing how hes "fixing fl" while he comes off as a perfect well put together guy but he has so many issues and he is totally unwilling to work on them himself even though he will humiliate her with a whistle or make her write a diary that he then reads keeping her from having any privacy. Tbh its very unhealthy.
I know he's supposed to be our ML and we should just forgive him because he's doing it for "love" but he basically treats her like a toddler and completely overpowers her in the relationship. He literally decides how everything will go with a detailed plan and blindsides her with it. She is a gentle pushover who is absolutely desperate for some affection so she goes along with whatever he says. Poor girl's self esteem and backbone are in shreds on the floor after all the shit he put her through and now he's still brow beating her into doing whatever he wants with their relationship.
