Diluc was never one to cry especially in front of you, he didn’t want you to worry think he’s weak

however… once he noticed how you would hang around keaya he knew you would never betray him but he started to feel more insecure thinking that you found keaya more attractive

it hurt it really hurt and he couldn’t stop himself from crying silently while laying beside you as you slept, after a while you woke up to hear him sniffling and crying it truly broke your heart
