Suguru is your best friend and you noticed he's been depressed after Riko death and the fight with Toji leaving him with trauma.
Satoru and Shoko don't seem to notice which makes you mad, because it obvious, he's lost weight and he always looks like he hasn't slept in days. You spend your free time with him making sure he doesn't hurt himself and that he feels like he has someone to talk to, but sometimes you can't be there for him. So you come up with a genius idea to get him. A cat! After reading that cats and reduce stress, anxiety, and depression you wanted to get him one, and it's also great because it's almost his birthday.
You spend days trying to find the right cat for him, you were about it give up until you find, Kuno, she is the sweetest little cat you've ever met she is a Maine Coon and Persian mix, she was a calico, she is still a kitten about 8 weeks old, and it's just in time because it's a day before his birthday. So you adopt her spending over 314292.45¥ (2,000 USD).
The next day you wake up and go straight to his dorm with the little kitten in a box with holes so she can breathe of course. You get to his dorm and knock on his door. A few seconds later he opens it, it looks super tired like he just woke up.
"Happy birthday, Suguru!" You smile.
"Oh uh I forgot it was my birthday.." He lets you in and you set the box down
"Is that a gift..?"
