Mark started off as a playboy and a homophobic (Mark expressed his disgust towards OuWen when OuWen touches him and more). On the other hand, OuWen and Mark couple focuses more on character development and how they grow together, as a couple and as an individual. Rather, the earlier episodes and every extra scene (Hsuan Yu's and Yan Fei's childhood scene) make their romance buildup more interesting and meaningful. But while watching the earlier episodes, you won't feel bored because you don't see their sweet moments. Therefore, all their sweetness is around the last episode. Watching the first couple, you will feel butterflies in your stomach (but slow butterflies), Yan Fei feelings realization towards Hsuan Yu comes rather slow.
The first couple's storyline is really sweet, it focuses more on how Wang Hsuan Yu unrequited love is finally being reciprocated, and how Yan Fei comes to realization that Hsuan Yu has been by her side this whole time. Love is Science? the premise revolves around two couples, one bxg couple (Yan Fei and Wang Hsuan Yu) and one bxb couple (Ou Wen and Mark). Though the plot is it’s rather cliche but it has a sweet atmosphere that makes you invested in it!! Plus, All of them have good chemistry, little misunderstanding.
No antagonist, the characters are just sweet and natural. Love is Science? is a slow but very heartwarming series. Romantic and Meaningful Love is Science? (戀愛是科學) is an 18 episode romance drama that revolves around 2 couples, Yan Fei - Wang Hsuan Yu and Ou Wen and Mark.
