But only because Juri is able to speak her mind, she's not that outgoing with her own feelings and she actually hates to share them with people. When there is such situations, where people ask if she's sad/angry/depressed, she tends to raise her mental capacity max high and never want show her weak sides. Juri begins to babble unneccesary words, just because her talking might become a way out of the, according to her, awkward conversation and lead into a happier conversation. But don't get fooled by that, Juri is actually a very friendly and social person, but sometimes she easily gets confused about her feelings and gets a bit unknowing/nervous around people who wants her to share them with them. Because she makes so much efforts into hiding her feelings and is so careful about it, she easily gets very tired and lazy afterwards. But it is not only with hiding feelings she does this. She often pushes herself to her limit, and later on falls down into a coma. This is Juris' way of handling things. Therefore she needs to rest much more then the other members after stages/concerts/shows, where feelings might show up all the time. The reason for her acting like this is because she always wants to make a good first impression on people, but also because she's afraid she might be considered weak or strange.
