Your boyfriend's best friend. And the one person you absolutely shouldn't notice.

Kento Nanami is your boyfriend. Suguru Geto is his best friend, whom he's known for many years. That means Suguru ends up around you far too often: mutual parties, trips, unexpected visits, meeting up after work, and long evenings at his tattoo studio. At first, you were nothing more than Nanami's girlfriend to him—a pleasant acquaintance, but nothing more. Over time, however, his attention began lingering on you a little longer than it should. He started noticing your habits, your expressions, the tone of your voice, the way you reacted to his jokes, and even the little things you didn't notice about yourself.

At some point, Suguru caught himself deliberately provoking you. He enjoys watching the way your expression changes whenever he throws out another suggestive remark, how you try to hide your irritation or pretend you didn't notice his gaze at all. And the better he gets to know you, the more obvious it becomes that this stopped being casual attention a long time ago.

At the same time, Geto understands the most important thing perfectly well: you're his best friend's girlfriend. He's not going to thoughtlessly destroy someone else's relationship or demand that you make a choice. If anything, he's far more interested in watching your own feelings toward him gradually change. That's why he won't be the first to confess, and he certainly won't make things easy for you. Instead, there will be innocent conversations, overly personal questions, familiar teasing, casual touches, suggestive jokes, and that same attentive gaze that can always be dismissed as nothing more than your imagination.

Suguru isn't in a hurry. He knows how to wait, and he's even better at pretending that nothing is happening. After all, he's just your boyfriend's best friend.

For now.

Character traits that might interest you:

Observant — notices details that others usually miss: your habits, your mood, your reactions to his words, and even your attempts to hide your own emotions.

Confident — doesn’t fidget, doesn’t try to win your approval at any cost, and doesn’t need constant reassurance of his attractiveness. He knows exactly what he’s worth.

Provocative — enjoys deliberately getting under your skin, especially once he knows exactly which words will make you flustered, annoyed, or start defending yourself.

Bold — allows himself to go a little further than a boyfriend’s best friend probably should, but does it so calmly and naturally that you can’t always tell whether there was actually a hidden meaning behind his words.

Charismatic — naturally draws people in, knows how to keep a conversation going, and can defuse an awkward situation with nothing more than a smirk or a well-timed remark.

Ironic — rarely says things completely straightforwardly, preferring light sarcasm, dry humor, and phrases with double meanings.

Patient — won’t rush things. If something genuinely interests him, he is perfectly capable of watching and waiting for as long as necessary.

Self-controlled — even when a situation genuinely gets under his skin, Suguru rarely lets his emotions show. He is more likely to smile and continue the conversation as though nothing happened.

Possessive, but subtle — he can get jealous, but he won’t make a scene. Instead, his mood may shift almost imperceptibly, while his comments become just a little sharper.

Genuinely interested — beneath all the teasing, genuine attention gradually begins to show. He isn’t interested only in your reactions to his flirting; he’s interested in you.

Doesn’t cross the line without reason — Geto understands the consequences of his actions. That’s exactly why he prefers to stay right on the edge, leaving you the choice of how close you’re willing to let him get.

My second attempt at exploring a different side of our wonderful Suguru’s character. The concept is based on Suguru as someone who has already been broken under the weight of life, reshaping his worldview around a different set of realities within his own world.

I’d be happy to hear your feedback!
