It's a story about the male protagonist's rebirth. The male protagonist was a scumbag in his previous life, and he's reborn as a student to find redemption. It's a sweet and pampering story, but don't step into the trap.
[The dissolute senior student vs. The cold and rational academic master]
In high school, Lu Shi fell in love with Lin You. His initial love was filled with guilt and paranoia, but his final love was sincere and flawless.
"Lin You, I like you." "Thank you."
"Lin You, I like you..." "..."
"Lin You, I ask you for the last time, are you willing to accept me..." "I'm sorry..."
"Lu Shi? Long time no see." "Long time no see."
"Lin You, I love you..." "Yeah... I know."
"Lu Shi, actually... I remembered..." "... Sorry"
"Lu Shi, don't you want me anymore!?" "..."
"Lin You, I love you." "What a coincidence, so do I."
"I wasted two lives just to give you back the happy years you should have had."
