Taecyooniverse theories

even before our couple joined FO2, they were very good friends..from the army episode, we know that yoona knows about taec's decision to give up his US citizenship to join the army cuz she teased him about it when they were all in the truck...even good friends will share such info...

at that time, both already had certain attraction for each other but didn't act on it..as the female party, yoona will definitely keep it to herself..girls are usually like that..only after the guy reveals his feelings then the girl will choose if she wishes to reciprocate...

yoona's suspected that taec likes her but only had that affirmed during the best friends episode when taec chose her over fany...at that point, think she was 80% confident of his feelings for her...it was also after that episode that taec decided to step up his game after seeing yoona's reaction to won hee's teasing of him & fany...

the wondergirl episodes sealed the deal for these 2...yoona's remaining 20% was in the bag after that perfume gift..haha..now i believe the couple is dating..loose ring in point..also, pretending not to know each other...that's utterly ridiculous if there's nothing to hide..
