I do recommend checking out the other series by the author of "For the Rest of Our Life" that author always does great works (though She's a little too into suffering and way too much family drama, like i get it family might not always support You but this author lets this take over her stories) "Stunned for You" and "My Feelings Can Wait" are her other two series both have great characters with tons of development and it's just damn lovely. 

"Love From The Male Protagonist Harem" is also great, but also has quite a bit of angst lol the mc is quite lovable and the heroines are all very likable. 

Falling in Love With Tsundere Villainess, had potential but just turned out above average, author kinda Lost Focus halfway it feels like, still very sweet and easy to read, it's short and both leads are quite lovable and likable with both developing throughout the series, especially the Villainess it's a joy to watch her bend lol though she can be a little irksome at the beginning.
