I felt embarrassed reading your comment.. I'm 22 years old and act just like her. Afraid of being in love, of a relationship, having difficulty in just... talking to the person I like...
Maybe people think I'm annoying too :/
It's just really hard to change when I've been like this since my childhood..

Her being shy isn't what's annoying to me, it's her withholding such an important fact about herself, that she has a serious illness, from her boyfriend is frustrating. Especially when he tries so hard, and communicates so much, and when she loves him, it feels like a disservice. Also, its a usual tactic to pad chapters I believe, not telling each other vital things, and building up to an avoidable conflict, which I dislike in stories.
As far as your behaviour, I too am a 23 year old who is too scared of relationships, and I was, till very recently, insecure and scared of life in general. So I get what you mean, and I know you can take your own time to improve upon things you think you need to improve on. As far as what others think, it took a while for me to really understand just how much people don't care about how you behave, its a passing thing for them to meet you. So best to not give a shit about that either. Good luck!
The female lead is frustrating me a bit. She is 26, she should know to be open with the prof, tell him about her illness and issues, or the fact that she loves him, or anything for that matter. She does nothing but blush and sound despondent about their relationship, it seems... I like how they are with each other, cute and accepting. But she is not honest when she had many chances to tell him, or give him any idea about what her condition is...
