"Why are you jealous again, baby? I told you, you're my only girl." Ryomen sighs frustratedly.

You saw Ryomen with a girl flirting with him. Usually, you would ignore it because even if you and Ryomen weren't together, he still made you feel special. You, however, caught him lowkey flirting with her.

Maybe you're insecure because your relationship with Ryomen isn't secure since he doesn't want to take things "seriously". But you can't tolerate his attitudes anymore.
