Is it just me or is there a weird love triangle going on between teddy, dong joo's sister, and that single father? I mean I think the older guy kinda likes her...you know...like like her.  In episode 13 (spoiler) he practically went up that steep cliff just to pick that flower for her and then he gave her an intimate look when she said that he was running too fast for her.  Idk tell me what you guys think.
