Both are my two favorite romantic comedies of all time with amazing acting, OSTs and love stories. Both are very touching heartwarming love stories about male leads with PTSD who push others away due to their fears of getting hurt again. In Woo Jin's case from 30b17 he thinks it's that he's afraid of hurting others again, but both are very mistaken about their traumatic incidents which the female leads help them to realize. Both female leads in their own ways haven't been able to live up to their brilliant younger selves due to life altering accidents and both shows are about how both couples help each other find the courage to live and love again. Shin Hye Sun is in my top 5 favorite actresses right up there with Gong Hyo Jin though Shin Hye Sun has only recently started getting leading roles. They are both so lovable as people and so talented as actresses. They both make me cry buckets of tears and laugh ridiculously loud and feel amazed by their talents both comedically and emotionally. They both become their characters so seamlessly that I can't wait to watch their next shows.
They are both romantic comedies with very sympathetic female leads who have to go through a lot of hardships to achieve their dreams. 30b17 is much lighter and is more comedic in tone and though the main male lead is also not very nice to the female lead at first, it was more coldness than the bullying that occurred in BOF. Both have great looking swoony male leads who start out as harsh and cold and eventually warm up due to the lovable and plucky female leads. Both have very caring second male leads who are always there for the female lead characters and were basically her first friends in the new world she found herself in. Both first and second male leads have very close relationships that get tested because they fell in love with the same girl though in BOF they both knew of their rivalry, in 30b17 only one guy knew that he was in a love triangle but both second leads had a moment of having to choose between their love for the girl or the guy.
Both are two of the cutest romantic comedies out there. Both have swoony male leads who start out as cold but warm up to be the most adorable BFs ever. Both have hilarious female leads who do physical comedy really well. Both will make you LOL and both couples have amazing chemistry though 30b17 couple is much more innocent due to their emotional ages. Funny coincidence, both female leads also acted together in Legend of the Blue Sea when Shin Hye Sun was still a second lead actress.
Both are light, funny romantic comedies with moments that will pull at your heartstrings and make you cry. The male leads are outwardly cold but are secretly softies inside. Both female leads are very naive for their chronological ages because Mi Nyeo from YB grew up in a nunnery and Seo Ri from 30b17 devoted most of her childhood to playing the violin before falling into a coma when she was seventeen years old for thirteen years due to an accident. Both stories revolve around music, Kpop for YB and classical music for 30b17, both in their own ways make both genres of music sound really enjoyable. Both stories involve the couples falling in love while living together and both stories involve the leads looking for very important missing relatives. Both OSTs are great. Both shows will make you laugh, cry and root for the lovable characters.
