After his talk with Li Yu that day, Che Haishen finalized the details of the collaboration with Zhang Yanlin, signed the contract, and then returned to school to immerse himself in music production.
Although Li Yu had provided Che Haishen with the lyrics and melody, Che Haishen still had a lot of work to do afterward.
Besides, strictly speaking, what Li Yu gave Che Haishen was just a lone main melody; Che Haishen still needed to determine the instruments, accompaniments, and harmonies during the arrangement.
In the Bratis Continent, Minstrels weren't so particular. Kieren, for instance, generally just relied on his Layakin; thus, the amount of advice Li Yu could offer Che Haishen was limited, leaving more room for Che Haishen to play freely.
Fortunately, the arrangement for a pop song was not complex, and Che Haishen managed to finish this part of the work in about three days.
As for the lyrics, he simply lured a roommate with a meal at Little Fat Lamb to solve that matter.
