Well, we have here different opinions, probably because we like different game styles. For me it's not "wholesome" when quite in the beginning the most interesting/beautiful girl in the game (who also kissed/hugged you at the very first time you even see her - for me therefore the potential li number one in the game so far) giving someone else of the group a bj right away. So you get immidiatly cucked in the game at the first release - for me not really nice. What a "wholesome" game start...I get that this game is definitely not Young Again.
But with regards to "wholesome": the MC seems a fairly normal guy. After moving to another town he joins a scouting group (not a swingers club). The members of this scouting group seem fairly diverse in terms of personality, but we don't know that much about them yet. We have one couple. Harem lovers may dislike that, but that's how it is in the real world. Pretty wholesome even, to use that term. We have one slut who likes to give blowjobs. Definitely not my type, but it's a free country: if she likes to do that, why would it bother me? The player can choose not to enter the room and if he does anyway he can choose not to get a blowjob. What bothers me most about the term "wholesome" but which people don't complain about, is the scene where Katie is drunk and the MC undresses her under the pretense of "not getting her top dirty". That scene felt a bit rapey, although it was also possible to play it like a good gentleman. When going too far, the MC got slapped (good for her).
So yes, the game is actually pretty wholesome. Normal guy meets a normal group of people, all of whom have already established relations with others.
As you also mentioned the "real world", there I would immidiatly leaving that strange scout group where at a birthday party from a group member some have (not very hidden) sexual action - for me that sounds more like a swinger club...
