The details I'm remembering:
- mc with dark hair just started uni when his home burned down
- asked his former (rich kid) classmate (white hair) for help
- former classmate offers to let him stay for free, if he acts as his dog = they engage in puppy play
- they live together, fall in love, yada yada yada, mc wins the lottery and becomes even richer than his bf and they live happily ever after I guess
Anyone know this title?
