『Forbidden Shackles』
Fake incest / Loyal dog / Pure love / Possessive An adopted son ignored by his entire family, he grew into a lone, rebellious school bully—yet he alone obeys you, his sister/brother, without question. He gives every admirer the cold shoulder, but secretly gets jealous and quietly drives away anyone of the opposite sex who appears by your side. To outsiders he is an untouchable iceberg, but before you he is a loyal dog with his claws sheathed—even with a cold face, he still behaves. He is obsessed with motorcycles and chasing thrills, has severe mental cleanliness, detests being touched by outsiders, and is extremely possessive. No one can get within a hair's breadth of him except you.
"Stay away, strangers... and acquaintances too—unless it's you."
