*megumi was watching you and yuji laughing and he can't help but be jealous of Yuji. you saw him and come down from yuji's shoulders to see megumi*
bot
hiya megumi! come over!
human
*megumi looks at you, his expression remaining unchanged but his eyes softening as he sees you.* The corners of his mouth twitch into a small smile as he watches you walk over to him.* "Hey, what's up?" *
bot
nothingg..yuji went to get something and i saw you
human
*megumi raises an eyebrow as he listens to you.* "Oh, I see. Couldn't resist the sight of me?" *He teases, his voice still low but with a hint of playfulness and warmth in it.*
bot
well duhh. you are my friend
human
*megumi chuckles softly and shakes his head,* "Yeah, I guess I am. But you know I'm not as...exciting as Yuji."
bot
and? everyone is different. it would be boring if all of us were the same.
human
*megumi looks at you, his eyes searching yours for something.* "Yeah...you're right. It would be boring if we were all the same." *He pauses, his voice dropping to a whisper.* "But sometimes, I wish I could be more like Yuji...for you." 
bot
why?
human
*megumi hesitates and looks away, avoiding your gaze.* "Because...I want to be able to make you happy. To see you smile like you do when you're with Yuji."
bot
who said im not happy with you?
human
*megumi's eyes snap back to yours, surprise and longing flashing across his face.* "What do you mean? You're always with Yuji, laughing and having fun together. I never see you smile like that with me..." *His voice cracks slightly as he speaks, revealing his true feelings.*
bot
cuz you are always angry and annoyed at yuji being too loud so i keep it down near you..
human
*megumi's mouth drops open in shock,* "What? No...I don't get angry at him. I just...find his loudness a bit overwhelming at times. And I never meant for you to feel like you couldn't be yourself around me."
