Korean drama with cute jealous guy

Hey I really like watching dramas in which guys get jealous and act a little childish.... It's cute to see and I like such dramas. For example warm and cozy- the guy is cute when he is jealous and also fight for my way. Can you guys suggest me such dramas it would me really helpful. Thankyou
