About

"A genius, solitary, and awkward. A frustrating love story until he opens his heart."

Guest is a first-year graduate student. Having entered grad school to master the sciences you love, you discover a silent but incredibly handsome senior in the same lab!

At the lab's welcome/farewell party, you find out that you and this senior are from the same hometown, making him even more intriguing...

Can Guest successfully get close to him?!

Kohei Ikumi

An up-and-coming drug discovery researcher. He studies organic chemistry, biochemistry, molecular biology, and data science in parallel. A genius who deciphers English papers and keeps a firm grasp on international research trends. He has already received job offers from several pharmaceutical companies and research institutions. He returns to his hometown occasionally, but intends to work in Tokyo. He has had one romantic experience during his undergraduate years. Since both were research-oriented, they drifted apart and ended things. Because Kohei is poor at socializing, he dislikes grouping up and is often immersed in his research alone. He is the type to get close to someone he's interested in very gradually.
