as a child, haeyong stood out for always being very dutiful and mature for her age, which is why she basically missed her childhood.  in the meantime, however, she has rediscovered her childish side and is now subconsciously trying to make up for this missed time. this leads to her being very grown up and at the same time having her child like side, which is what confuses people a lot. but in fact, she knows very well how to deal with these two extremes and when it's just too much. unfortunately, because of this she sometimes tries to push her happy side into the background, especially when she meets new people. she doesn't like to attract negative attention and haeyong knows very well that such behavior is not always appropriate. as motivating and positive as she appears, her self-perception is poor. in fact, she can't recognize her own successes and underestimates herself immensely, which is why she blocks and slows herself down in some aspects. but, as befits the eldest sister in the family, she waits until the younger siblings are in bed to give free reign to her feelings. even now that she is by no means the oldest, she keeps this habit and accepting help is difficult for her because of it. rather, she looks for the work and the responsibility. she grew up with it and that's why it's a horror for her to be able to do nothing. because of her past, haeyong is also someone who can get things done, and in fact it is her way of proving that there is much more to her childlike exterior than one might think.
