Taking from the comments of @Saintsovereign the True Social line will be non-romantic, purely social.
One part of the line will probably be subs developing long term traits and skills like the storytelling and adventurism in Daredevil, Inner Circle for networking and maybe True Social as the quintessential sub for understanding, connecting and negotiating in whatever circumstances and with joy. (for party people, socialites, therapists, politician etc.)
It would make IMO a lot of sense to also develop some short term, light, narrow focused subs in the line, conceptually not too dissimilar from the old Love Bomb but maybe a bit more pointed: Just the short boost you might need for one specific meeting or a very limited period of time. Your life goal might be world changing inventor, MMA fighter or reclusive artist, but there always will be this one difficult family meeting, the wedding or an important job interview you need to handle and some of these social gatherings will come without much notice.
These subs should be very narrowly focussed (no ME), high dosage (Terminus?), short (1 min.?, 3 min.?), used when needed and probably aura heavy (e. g. warm & approachable or adored center of the party or reputable & competent).
I am not sure which structure would make sense. Maybe a multistager, each stage for a specific occasion, like a subliminal first aid kit?
