{Teach Me (BY) Sequel/Spin-off} … Byun Baekhyun. A young and a very respected businessman in Japan. He is known to be very successful in such an age. People around the world gave a lot of compliments and good remarks at the success of the guy. For four years, their company had been massive, earning a lot of profits, big time investors and best shareholders. But what the people didn't know, is his unbearable and painful past. Deception is the act of making someone believe something which isn't true. A big lie. It is the act of deceiving someone about something that is a lie. Baekhyun was in a self-deception. He keeps telling himself what he wanted to feel, convincing himself something which he wasn't even sure if it was true. Until... The past collided with the present. Pain and Glory. Failure and Success. Thorns and Roses. A massive collision. A change in the future. Is it just a Languish Deception? Or is there something more?

Byun Baekhyun. He thinks that he's perfect. He thinks that there's nothing that he could wish for. That there's nothing that he need to look for. With the people who loved him and the person he loves with his side, he can't look for anything anymore. He thinks that he is already complete. But the only person he thinks that could make him happy is the girl that he loves the most. Taeyeon. He loves her. He thinks that she's already the one. The one that would be his life and would be the life of her life. But what would happen if a certain guy would come into his life?

Baekhyun falls in love with someone he can't have; Chanyeol. His love for Chanyeol puts their best friend relationship at stake. Chanyeol was the greatest and worst thing that happened to Baekhyun.

Chanyeol is a very known player in their school. He dates girls and, not to mention, some guys and dumps them after he gets bored. He is also known for having a good reputation in the school. He may not be perfect but his imperfections made everyone love him so much. But, when a certain teacher came in to his life and told him (in his face), how much a shameful person he was, he felt that he needed to do something about it. He thought that it was his time to teach him. Teach him how to fall in love and break his heart after. Will he break the teacher's heart just like what he always do to the others? Or will it contradict to how he wanted it to be, and instead he will teach himself how to fall in love? Or maybe, they're just not meant for each other and fate will contradict to what they want.
