If you like someone, and you're serious about it... what would you do? If they accept/ reject... what would your response be?

Confess to him. Hahahaha okay srs. I'll tell him that i love him and i'm srs. But if he reject and he said that he love someone else or he in relationship with someone, so i think i should move on bcs i dont want to be 'perampas' or orang ketiga 😅 but if he reject me just bcs he doesnt love me, em maybe i'll try to confess again next time 😅😂 tapi kalau nampak sangat dia memang tak suka tu, i dont think i'll confess again hahahaha just move on. Walaupun kita tau move on tu susah 🙇
