Sein Julian Schvagenbagen

Sein is the Second son of Gustav Schvagenbagen, younger twin of Sebastian Schvagenbagen and youngest brother of Lydia Schvagenbagen.

But Unlike Sebastian, Sein is the 'Perfect Son' and Gustav's favorite in the family.

Sein is a talented and smart boy, The only problem is, He's too kind and humble for his own good

Whilst Sein being Father's Perfect son, Sebastian is always overshadowed by Sein always compared to him by their father, Gustav.

Sebastian on the other hand, isn't 'naturally' talented like his younger twin Sein, He had to work hard for it.

Though this is why Sebastian envious distress starts to emit.

Sebastian and Sein are identical twins yet very different at the same time.
