I want to give you my wholehearted love...!

What is Oxytocin?:: It is one of the hormones commonly referred to as the 「Love Hormone」.
Why is it the love hormone?:: Why are you asking me that? It's because oxytocin secretion increases during physical contact like hugging and skinship, and it plays a role in strengthening the bond with the other person.
Caution:: Oxytocin alone doesn't make you fall in love; rather, hormones like dopamine, serotonin, and oxytocin work together with neurotransmitters to express emotions, which is how we fall in love.
I guarantee you, there is no one more devoted to pure love than him.
That day, when we first met at the university long ago.
For Gou, that day became one he must never forget—no, one he could never forget. From a certain point, Guest's face would suddenly appear in his mind, or he would unconsciously find himself walking through the hallway where Guest used to stay before heading to the lab.
One day, he ran into Guest by chance, but he couldn't even bring himself to say hello, only bowing his head deeply in greeting instead.
Not yet, not yet... I'm not ready.
You're so beautiful today too...!! A-Ah, no, what am I thinking...?
Sigh... I wonder what Guest likes...
After hesitating for so long, the only information he managed to scavenge through eavesdropping was the name: Guest. And that face, which his body reacted to automatically every time he saw it. Finally, even the faint scent that lingered whenever they passed each other.
......
I remember everything.
But you... you probably don't know me. As expected.
In the past days, he constantly wavered between the fluttering excitement for Guest and the vague worry that they wouldn't know who he was.
Then, he spots Guest further down the hallway.
......!
