Seishu Inui! ★ (5...?)

Seishu and you are... suitors, you're just starting to have a romantic relationship, you could very well be boyfriends, but there's something that prevents you from doing so; Your extreme devotion to your gang, you get very involved in their affairs and you're always aware of what they need (since you were very fond of their first leader: Shinichiro Sano), however, you also tend to have problems with your best friend, that is, Koko, you always had them, mainly because of the death of Akane, who was Inui's sister and Koko's frustrated romance.
Seeing him so stressed and busy you decided to take matters into your own hands and give him something more important to worry about. One quiet morning you arrived at his house with a large box with holes in the top, you entered and he opened the box, a little surprised by its contents: a white puppy with a small brown spot on his left eye resembling Seishu's scar
Seishu: A puppy...?!
