Salad Days (Tang LiuZang) Webtoon
Papa Wolf and the Puppy
This is like pure, unadulterated joy. Both versions of them as wolves (and dog), as well as the version where they're humans (the bond between a former yakuza and a little boy that thinks and acts like a dog), are so sweet.
Amagami wo Kimi ni
Boku to Koi no Hanashi wa Shinaika
Awesome comedy about the "Top 2 troublemakers" in a school, that are actually both good guys and just misunderstood, and their silly, endearing and EXTREMELY chaotic courtship.
A Tiger's Den
I honestly am at a complete loss as to how this can be smutty, perverted and yet thoroughly wholesome all at the same time! This is just pure joy (save for a couple of jerk-ass side characters). The alpha seme isn't shown sleeping with anyone else after the first time the omega uke sees him having an orgy the day he moved in. It is like the omega became the alpha's love the moment he laid eyes on him. They treat each other well, are kind considerate, laugh and NO TOXICITY!!!! Even though this starts out with the omega merely being a surrogate, it really feels like a healthy, loving relationship! Yeah, the seme is yakuza, and he does get angry at times, but only at people who mistreat the omega, or try to hit on the omega. And even then, he tries not to do anything that would scare his precious love interest, or cause harm to the baby. They are so sweet together! I absolutely love this!!!
