Yeah it's basically a cute love story of 2 boys who have been together since childhood. We have seen many such similar plots but this plot is quiet unique.
First of all I loved See-Eiw and Cake's chemistry. It seemed so natural. They were closely knit since childhood and the level of comfort they had with each other wasn't just that of ordinary Bromance. They always slept hugging each other. Both helped each other in their own ways. We saw that even when the phase came where cake had a girlfriend and was busy with her, he always cared about Eiw. Though Eiw felt neglected and hurt at times, whenever Cake felt like Eiw was upset, he always asked him..."are you angry..what's the matter"... At the time when he was about to leave for America, he prioritised Eiw and spent time with him, even at the cost of breaking up with his gf. After he went , I thought, maybe like most storylines, they will eventually lose contact and get busy with their own lives. But no! They stayed connected for all those 4 years, patiently waiting for each other while improving themselves. Eventually, Cake also realised that he was in love with Eiw and they became a couple. ACTUALLY, THEY'VE ALWAYS LOVED EACH OTHER. THEY'VE ALWAYS BEEN EACH OTHER'S HOME. ONLY THE RELATIONSHIP STATUS CHANGED FROM FRIENDS TO BOYFRIENDS, WITH A ROMANTIC ASPECT ADDED.
THE DRAMA ALSO FOCUSED ON QUITTING TOBACCO by showing how Eiw's mom had to die due to passive smoking.
Overall, IT WAS A HEALTHY DRAMA. THERE WAS SO UNNECESSARY LOVE-HATE RELATIONSHIP, THERE WAS NO DELIBERATELY MAKING EACH OTHER JEALOUS/MAD , HURTING EACH OTHER, THERE WERE NO TOXIC SECOND LOVE INTERESTS AND UNNECESSARY PARENT ISSUES. IT WAS OVERALL A VERY LOVEY-DOVEY WITHOUT BEING CRINGE TYPE OF DRAMA. BUT, IT WASN'T ANYTHING NEW, EXCITING OR EXTRAORDINARY. SO MY PROBABILITY OF RE-WATCHING IT IS PROBABLY LOW. BUT OVERALL ITS A FINE DRAMA.
