There is not many good actors available in Enxi's age range that's why they paired her with older actor. Pretty sure the crews were aware pairing a minor with an adult would stir controversies that's why they toned down everything including not having kiss scene or other intimate romance stuffs. everything in this drama is kids-friendly. They filmed this drama with Enxi's parents' consent too, everything is under control, nothing crossed the line and there is no weird thing like some people's assumptions lol
The scriptwriter lucked out with Park Bo Young, Seo In Guk, director and OST singers. Maybe because I've watched too many dramas hence this drama feels bland and boring. I wanna drop this but I love Park Bo Young for too much, I will continue just to see her.
sometimes i think the way director filmed the drama isn't that good. it affects the whole atmosphere, sometimes the acting feels awkward because it doesn't fit the atmosphere (but judging from the scenes and dialogue you know the actors/actresses are supposed to behave like that, unfortunately the way camera filmed it felt so bad and cheap like soap opera, resulting their actions seem too fake and bad at acting)
