1. MC's character is very deep, mature and understanding just a "tsundere" otherwise why would he posed on ML after having a time travel/dream of future only once since considering him bitter rival for two years straight

2. MC's being all dorky and adorable by getting revolted with the idea of him being at the bottom and might get divorced like the case of another couples news he got from his friend

3. And of course MC's constant behaviour of avoiding ML (it was really sexy and very responsible for his actions) despite him taking the initiative every single time approaching/gazing/touching whether sober or drunk. Especially that moment when he himself boldly claimed ML's his wife of future internally and kissed at the haunted house yet after being embarrassed decided to avoid ML. Also another bonus scene when ML's mother told him ML's liking him back but him being all shy and naïve with the ML even though he slept with him at the same bed at his house after deciding to stay and before during winter camp

4. Lastly my emotions were stirred to it's peak when the way MC showed his support and being concerned about ML's situation after knowing ML's being harassed in the past by another omega for his status and again being harassed by that ZHUANG guy while they escorted ML to the hospital where MC acted all confused and muddled headed with only one thing in mind that is ML being an S class Alpha all from the beginning regardless of his health and mental issues wreaking havoc. MC was so supportive that he even left the hospital and didn't wait for the ML to wake up (when he could stand stay with the ML at his house after party) and never even bothered to call him up to ask about his situation as a human courtesy, as MC was being busy with confused and unsure how should he feel about ML being an Alpha and also kinda feeling proudness around students who were gossiping about the ML incident. This support totally surpassed and rivalled the concerns and assist ML gave him while dealing with MC's past ab*ser as he only beaten him and sent him to jail while constantly checking and making sure he was all right through out the time and never once left his side. Or warning the ZHUANG guy to never come near MC, while always getting protective of MC during his troubles with other small canon fodders.

MC - for me, he's a 3D character. Good thing, the author put some backstory to him, making him more-human? Some short novels I've read focuses more on plot, but this one focuses on the MC's journey toward healing (about why he doesn't like to study) and plot. Overall, this kind of MC is breath of freshness after reading dog-blood novels. For the ML he's good! He's the 'wife' and know how to respect their partner. I can't say anything bad to him 'cause he's good. He's also studious. One last thing is the villains. I don't like how the author dismissed them. Like how the tutor, as well as the victim-blamer omega, get their punishment. It was very lacking to me. It was dismissed as simple transferring of schools (for the omega) and jail (for the tutor, it was stated implicitly).
