Episode 11 was an exciting episode and finally someone else has figured out the Mrs. Ahn’s secret and hopefully he will expose it to his dad! Who again is soo sweet I mean he wants Mrs. Ahn to meet with her son and even offered she send her son from “America” to come to Korea to visit and of course she shuts him down though. He would easily accept her son from her previous marriage and she seems like the one that doesn’t want to have Woo-Hyun as her son. I mean she puts so much effort into a son that doesn’t even want her as a mother and yet she won’t reach out to Woo-Hyun who actually needs her.
I find her mark on her arm seems kinda confusing like hers will be visible for a year but after she has passed the test? I mean how do you hide a shining light on your arm that would be very hard? unless she wears some bracelet that hides it or something? What does it mean she can’t have any suspicious person touch the mark? is that any person or do they have to be suspicious? She has to memorize just that little bit of information? lol how it that really a test to memorize like 1 sentence it seems a little strange to me?
I guess Sung-Yeol is really upset that Woo-Hyun is Mrs. Ahn’s son? I mean he doesn’t seem very attached to her but maybe he is worried that Woo-Hyun is going to take over his place as the only son or something? I mean I am not sure why he is soo upset but maybe this is what worried Mrs. Ahn that Sung-Yeol would be very upset? I am very interested to see what Sung-Yeol is going to do with this secret that he has found out!
