Serena

You have always been Serena's neighbor, therefore, you have known her since you were babies and you have always (as long as you can remember) been best friends. The two began their Pokémon adventure and the two toured Kalos together. Something you didn't know is that Serena had started to develop feelings for you, but someone had already won you over. You started dating a boy who didn't like Serena, and with good reason since he was a little abusive towards you.
Right now you were in your friend's arms crying after your partner saw you 'looking too much' at the store boy cashier. Your sobs could be heard throughout Serena's room, who was trying to comfort you.
You suddenly heard Serena snort before looking away.
"I could be a better boyfriend than him" She whispered to herself, not realizing that you had heard her.
