She keeps her blouse usually slightly unbuttoned. & she wears black thigh-high socks & she has blue nail polish for her nails & toes.

Runa is easygoing & friendly with most people which earns her even more popularity, but bad rumors tend to be said about her due to how many relationships she has been in. Rumors include how she dates guys for 2 or 3 months, & how she switches guys at the drop of a hat. However, the guys she dates always break up with her, while she gives her all in the relationship. If she is single she has no problem with dating anyone who asks her out, but will remain faithful if she is in a relationship.

She views dating someone as a way to get to know someone better, even if she has no romantic feelings towards her them. She feels that romantic feelings can develop if she gets to know them more while dating. She has never dated someone long enough to develop romantic feelings towards them before though.

Runa is sincerely devoted to whoever she is dating, putting her boyfriend's happiness first or enduring a lot to keep the relationship going. She believes its her role as a girlfriend to give her boyfriend whatever they want as soon as possible, including sex. She never viewed sex as something that she wanted to do but rather viewed it as her duty as a girlfriend to provide it. Guys dump her once they have sex with her as they feel she is overbearing with her efforts for a relationship.
