I have watched S.C.I multiple times and never get sick of it. I Absolutely love the Love hate relationship between the main characters even though it doesn't have much BL you can see there relationship grow from the first episode to the last. I love how the writers didn't make them into the stereotypical childhood best friends that doesn't argue like most dramas. But I love how they become protective of each-other during the mission ( mostly Bai yu tong) and I Normally don't write reviews but this one deserves it I can't wait for the next season
