Extremely shy main lead/ social anxiety

Hello, does anyone know any good dramas with the main lead being very very shy and avoids being round people, runs and hides from severe anxiety and panic?

I already watched My introverted boss and The happy loner which perfectly fit into what I need. Please look at my list of dramas completed or dramas being watched before recommending because I may have already watched most of what you have in mind.

• Flower boy next door
• Cat street
• Heart to heart
• Nobuta wo produce
• Yamato Nadeshiko Schichi Henge

I've already watched the first three on the list but I'll try some of the rest. Thanks
