Koibito wa Hatsujouki
The 1st story about the delinquent being protective of the teacher was cute (until the clothes flew off randomly). Ditto the dog shapeshifter one. The rest... wtf.
Ore No Tenshi Wa Mayonaka Akuma
Main story about the cute student with the devilish older side and teacher with the scary face but cute personality is adorable & surprisingly heartwarming. Includes a psychological/disturbing one shot about half brothers.
Reverse!?
Kishima is adorable, protective and sweet - the best type of seme tbh. The teacher is a brat and more child than Kishima, but overall it works out.
Gravity Eyes
Meh, I so wanted this to be good but it turned out to be the typical "cold seme with painful past who has difficulty loving" and "uke who falls in love super quickly & heals seme with his desperate pushiness." It wasn't remotely believable that Kyouya supposedly had this massive crush on his benefactor, only to transfer it SO quickly to Kiriya in the space of a few weeks. Worse, Kyouya turns into the worst type of weepy/pushy/jealous/nosy uke who demands that the seme tell them ALL about their past painful love.
