Throughout the novel the protagonist references the love interest having had sexual relationships and makes alludes to not all of them having been consensual. Additionnally, the love interest sexually assaults the lead several times (e.g. tearing his clothes off, shoving him onto bed and threatening to rape him etc.). There is at least one instance in the extras where the lead is hurt and bleeding during a sex scene, yet the love interest does not stop even when he is asked to, suggests the lead says something he finds deeply uncomfortable for the love interest to stop, then demands the lead says it again several times and yet does not stop even after that. While the authorial intent is clearly to show that the lead is secretly enjoying the sex, it is not conveyed properly and the whole scene reads as marital rape. Also, the love interest manipulates the lead's emotions to pressure/coerce the lead into sex practices the lead is clearly uncomfortable with. There are several instances where the love interest directly disregards/ignores the lead's words when the lead says "I don't want to/I'm uncomfortable with that". A story is written by a female character depicting the two male leads in a romantic and sexual relationship. This can be particularly upsetting since at the original time of its publication the love interest was only around 15-17. This story is referenced multiple times throughout the novel and it used as a point of comedy. Other characters speculate that the lead had a sexual relationship with the love interest back when the love interest was a teenage and the lead was his teacher. This was untrue but still offhandedly mentioned a few times. A male side character is hit with an aphrodisiac in one of the extra chapters. Nothings comes of it and it is used for comedic effect. At the end of chapter 14 the love interest activity assaults the lead by pinning him down a threatening to rape him. Even as an empty threat it is quite uncomfortable to read. At the end of the novel there is a plot relevant sex scene that neither of the main characters consent to. The love interest is under the influence of an external source and is not fully conscious or aware of his actions, and while the lead does consent he truly didn’t have any other option considering it was either they have sex or the world ends. It’s quite uncomfortable to read and was not enjoyable for either of them. The scene can be easily skipped past. (Chapter 21) The extra chapters at the end of the novel contain multiple sex scenes that may be upsetting. Full consent is given but some people feel as though there’s manipulation at play since the love interest tends to play with emotions to get his way. All my with that the lead is an unreliable narrator who will often go out of his way to claim he isn’t enjoying something. Both of these things are again for comedic reasons but some people find them uncomfortable. (All of this information is based off the English publication by Seven Seas.
