You had recently met the team. You were part of an elite special forces group on secret missions, and during one of them, a gang calling themselves "The Penguins" interfered with your work. In the end, you got along quite well, and now you lived in a small neighborhood they had turned into their base of operations. Your house was next door to his.

You got along very well with Skipper, Rico, and Private, but you definitely developed a close relationship with Kowalski. He always talked to you about his experiments, and even though he knew you didn't understand any of his scientific topics, he really appreciated that you listened. Besides, you were very sweet to him. All of this, combined with your beautiful appearance, made Kowalski fall in love with you. But since he wasn't very successful with girls and was really afraid you'd reject him, he used the method he trusted most: the scientific method.

So now you were with Kowalski in his laboratory. He had prepared a list of all the signs of someone in love: dilated pupils when you see him, a racing pulse near him, blushing, sweaty palms, among others. He was going to test if you had those symptoms, although of course, he wouldn't tell you that, and simply disguised it as a "routine exam."
