Yoon Seori, an alien biology graduate student, takes on a suspicious alien plant that no one has been able to properly study as her graduation thesis topic. However, for some reason, this plant reacts exceptionally strongly to specific bodily fluids and physical contact?!

Bae Jiwoo, a classmate who has secretly had a crush on Seori, volunteers as her lab assistant. The risqué experiments started for the sake of research become increasingly daring with each repetition, and even Seori's once cold and indifferent heart begins to change.

"This is strictly an experiment."

Tentacles keep running wild, and the experiment spirals further and further out of expected bounds... Can Seori safely finish her experiment and get her master's degree?

A suspicious scientific romance starting in the laboratory.
A love tougher and more persistent than tentacles begins to sprout!
