Is it have a love triangle or SA from other main couple ?

There's no lobe triangle, and no 2nd main couple. But there's a lot of trauma involved, abuse both mental and physical, and ther will be rape, bottom guy, brother of ML will assault MC. Other than that I cannot remember if there's any other case of rape. Story is very, very complex

Omg
Thaks for saving me from reading it

It's actually worth reading, not your usual romantizes abuse, rape and shitty MLs. But considering themes it's handling, especially mental health topic, better stay away if it can upset you (╯︵╰,)

Theres no rape between main couple, it is the shitty side character who assaults the mc. Everything between the main couple is consensual.
