The story hasn't really gotten that far to be honest. All we've seen is how the two main characters met, who they were/are linked with romantically (Pinkie and Woohuis ex bf), who likes them (e.g. taekwondo girl), and the somewhat slow development of the two of them having interest in each other. With Woohui (brown hair girl) she's starting to show feelings for Jiho (blue hair girl) and its getting very obvious. But Jiho currently says that she likes Yeonwoo (Pinkie) and that Pinkie is her type and they are sleeping together but not dating yet. Despite that, Jiho makes some questionable statements at times about Woohui. For example she makes it seem like she would have some possible interest in Woohui but its only if Woohui would reciprocate or be open to considering her (Jiho) and this is what Jiho does not seem to believe is possible because to her Woohui is straight. Other than those comments/questions about Woohui, Jiho isn't as obvious about showing romantic interest in Woohui. To me she doesn't show any romantic interest in her and when she does it comes across as joking statements. What she does make very obvious is 1. She likes being around Woohui, seeing her, talking to her, going places with her etc... and 2. she's often concerned about Woohui like if something is going on with her. So you can see she clearly cares for her friend. 3. Jiho thinks Woohui is very beautiful to the point she seems to believe shes too good for all the male population at their university...
Outside of her concern, wanting to be around her friend, touching her boobs on occasion when offered up the chance... and a few comments here and there... Jiho doesn't reveal much in the feelings department.

I'm losing my track of the story
What's happening why such incidents happening
Who thinks what
Did not missed any chapter even read some twice in last few updates but I just can't grasp any of it -_-
