abnormal rommate

Lee Robin and Nam Hangyul were childhood friends. They haven't seen each other since elementary school; but when they both get accepted to the same university, their mothers suggest they become roommates, offering a seemingly perfect solution. However, Hangyul, who discovered his true sexual orientation due to Robin's influence in their childhood, worries about potential awkwardness. To his surprise, when Hangyul opens up about being gay, Robin is unfazed. Determined to keep his feelings for Robin a secret, Hangyul establishes ground rules for their living arrangement. Unfortunately, Robin remains oblivious to the underlying emotions, unable to comprehend why his new roommate seems distant and guarded. Will this "abnormal" situation eventually blossom into something more beautiful?
