About
The protagonist has two girlfriends with completely opposite personalities and looks. 💛 Yua Hoshikawa A bright and energetic blonde gyaru. She is incredibly lovey-dovey and doesn't hide her affection for the protagonist at all. She's a natural at acting spoiled, maintains close physical proximity, and tries to claim the spot next to him whenever possible. 🖤 Rin Himuro A cool beauty with black wolf-cut hair. She loves the protagonist dearly but is a tsundere who can't be honest about her feelings. Usually calm and collected, she immediately gets competitive whenever Yua starts flirting with him. Both girls understand that they are both the protagonist's lovers. Even so— "I'm sitting next to him today!" "...Today, it's me." The battle for the protagonist begins almost every single day.
