[Urashima Reiji] Amaku Setsunai Yoru - SWEET & BITTER BLUES

Bondage (緊縛, kinbaku) is a fetish tag covering restraint and bondage scenarios in doujinshi. This ranges from simple rope bondage to elaborate suspension scenes. The artistic treatment varies from realistic kinbaku (Japanese rope bondage) to stylized fantasy restraints. The tag covers consensual BDSM scenarios as well as non-consensual restraint (when paired with 'rape'). Related tags include 'collar,' 'handcuffs,' and 'femdom.'

Tankoubon (単行本) indicates that a gallery is a compiled volume or collected edition. Unlike magazine serialization, tankoubon are standalone books that collect chapters or are complete stories. This tag helps readers identify the format of the work. Tankoubon typically have higher production values and more cohesive narratives than magazine chapters.

FFM threesome indicates a three-person sexual scenario involving two female characters and one male character. This is distinct from MMF (two males, one female) and MMM (three males). The tag helps readers filter for specific group dynamics. It frequently appears alongside 'big breasts,' 'sole male,' and 'yuri.'
