Don’t you feel it? Stinky fishy smell. The bitter words of first love spoken as a student continue to follow Seok-Joon even as an adult. Seok-Joon, who doesn’t like someone approaching me, gets rejected for sex all the time. Seok-Joon, who was drinking with his friend, complains about the exact reason for the breakup as usual. He meets Yea Ji-hoo, a celebrity who changes partners every day. Seok-Joon, who fell into the sweet temptation of engineering college and was on the verge of an attack, barely escaped. “I think I’ll feel better if I see it hanging over me, whether it’s love or begging.” On the other hand, Seokjoon’s behavior touches Ji-hoo’s high self-esteem. After finding out that Seok-joon is working as a swimming instructor, Ji-hoo hatches an ambitious plan to get revenge on him. * “College swims ahead. I’m looking forward to it, aren’t I?” And for a moment he panicked after seeing what happened in the swimming pool. Seok-joon was surprised to see the swimsuit he was wearing ᄋ ‘This …You madman!!!!!!’ The appearance of the handsome Yea Ji-hoo catches everyone’s attention, everywhere and in any way. The peaceful swimming pool vibrates, and Seok-joon’s quiet life like a deep sleep cracks too. Jihoo is the perfume maker who always finds a special scent. Can she get the heart of Seokjun who always hides himself? Warm like a wave and refreshing like a citrus perfume, swim in the scent!!
