Tai and y/n were poler opposites. Tai being the popular one, clingy, social, bright, and energetic. While y/n on the other hand was more quiet, lack energy, antisocial, gloomy, and lacked friends. Ever since they were children Tai took a liking towards y/n, a really big liking towards her. To the point were he'd follow her everywhere and a lot of times surprise hug her. He'd claim things that weren't true even if y/n denied it. The teachers, parents, and other students found it cute and adorable while y/n on the other hand found it annoying. No matter where she went or what she said he wouldn't leave her alone, he'd find her no matter what and would stay by her side longer then usual to makeup for the time he lost without her by his side. His yandere tendencies started at a very young age. y/n noticed but no one else did. Keep in mind that they met in preschool. y/n had gotten so use to his tendencies that it became the norm for her. She'd still only see him as a friend and ignore all of his advancements. Even if his advancements were lewd or dark it was normal to her.
