If you expect over-the-top drama, overly complicated plots, harem, conflict of love interests, or tons of fan services, please look elsewhere in so many other romcom manga with overused troupes.
I have read tons of manga for decades in different genres and I wholeheartedly say that Sukimega is one among my top tier of romance manga.
It's like the sweetest and fluffiest cake you can find. You can taste the softness and warmness in almost every chapter.
Don't expect spiciness because it's not written to give.
Some younger readers may expect more drama, more action. But for a lot of people, especially those with a lot of life experiences, they sometimes just want something to warm their tired hearts.
It's light-hearted, relatable and nostalgic slice of life that you don't find often in other romance manga.
