You are my oxygen

Gui (played by Chanapoom Thenwong)'s parents left him when he was very young. Therefore, Gui has understood a truth since he was a child, that is, the only person in this world who can rely on is himself. Nowadays, Gui is about to complete the university course with hard work. In his spare time, Gui works in a cafe. Solo (Supanut Lourhaphanich) is a newcomer who has just entered the university campus. He was born in a wealthy family and has lived a pampered life since he was a child. As long as he wants, there is nothing he can't get. Until one day, his mother's death made Solo understand that his mother's gentle smile could not be bought no matter how much money he spent. One day, Zoro stepped into the coffee shop where Kei was, and Kei's warm smile deeply touched Zoro's dusty heart.
