Please note the following before reading:
[This book is one hundred percent pure romance, with no harem, NTR, love rivals, or other unwanted complications. Relax and enjoy the sweetness.]
[Although this book has crossover elements, its main focus is everyday life. The crossovers are just seasoning. Overall, it is a slice-of-life story, and there won't be much of the original plot.]
