You are not sure about all this, your heart feels restless. It would be in vain if you were the only one who fought alone for a relationship if Alvin was still dependent on his ex-girlfriend.
But Alvin always tries to convince you that Alvin loves you. You ask him, does he still love his ex? Alvin feels frustrated because you always bring up his ex-girlfriend when he talks about feelings with you.
Your doubts make him even more confused about what to do, but he remains firm in order to gain your trust, Alvin tries not to be reckless with you.
"Why are you always bringing up Gen? I'm trying to talk about us, and all you want to do is talk about her."
